ABSTRACT

French liaison consists in producing a normally mute con-sonant before a word starting with a vowel.Whereas the general context for liaison is relatively straightforward to describe,actual occurrences are dif?cult to predict.In the present work,we quantitatively examine the productivity of20liaison rules or so described in the literature,such as the rule which states that after a determiner,liaison is com-pulsory.To do so,we used the French BREF corpus of read newspaper speech(100hours),automatically tagged with morpho-syntactic information.The speech corpus has been automatically aligned using a pronunciation dictio-nary which includes liaisons.There are90k liaison contexts in the corpus,about half of which(45%)are realised.A bet-ter knowledge of liaison production is of particular interest for pronunciation modelling in automatic speech recogni-tion,for text-to-speech synthesis,descriptive phonetics and second language acquisition.

1INTRODUCTION

French liaison consists in producing a normally mute con-sonant before a word starting with a vowel,a mute h or some glides.However,this general description of the con-text of liaison does not allow us to predict actual occur-rences.Traditional accounts of liaison in French,mainly found in orthoepic textbooks,distinguish between liaisons that are termed obligatory or compulsory,those that are referred to as optional or variable,and those that are de-scribed as forbidden,erratic or impossible(cuirs,velours, pataquès).It is noteworthy that a number of set phrases belong to one class or another.But these domains depend on a range of stylistic,socio-linguistic and situational fac-tors.Possible liaisons may be mandatory in a poetic dic-tion or in a theatrical style,whereas in a colloquial use they sound shocking[5].Furthermore,this is liable to change over time[10].For example,in his revision of Delattre’s [4]classi?cation,Encrevé[6]ranks monosyllabic adverbs and prepositions in the variable category.Although this is not clear-cut,the linguistic resources and tools we dispose of may contribute to establish a new classi?cation.They enable us to obtain a more precise picture of current prac-tice,by producing the percentage realisation of liaisons in a large speech corpus,broken down by syntactic contexts.

In an earlier study[2],we described the occurrences of li-aison with respect to word frequency:an important correla-

tion could be found between liaison production and lexical

frequency,but we underlined the importance of relating li-aison to morpho-syntactic information.

Liaisons are of particular importance for pronunciation modelling in automatic speech processing.They allow for

a variable number of phonemes and can thus be considered

as sequential variants.As far as speech recognition is con-cerned,if liaison is not properly accounted for,then recog-

nition errors are likely to occur.Liaisons can be represented

either directly in the lexicon,as phonological rules,or im-plicitly in the acoustic models.The?rst option is generally

adopted,but a straightforward solution which consists of adding optional liaison phonemes to all applicable words

has proven ineffective.Recognition error rates did not re-

duce:the large number of variants introduced additional homophone sequences and introduced new errors.

The aim of next sections is to increase our knowledge of actually observed liaisons in a large corpus.In the

present work,we quantitatively examine the productivity

of roughly20liaison rules described in the literature.

2DESCRIPTION OF LIAISON RULES As mentioned earlier,the liaison phenomenon consists in the realisation of a normally mute?nal consonant in the

context of a following word which begins with a vowel.

A simple example is the word sequence les enfants(“the children”,pronounced in isolation as/le/and/?f?/),which

has to be pronounced/le z?f?/:/z/is the liaison consonant,

which is used as the onset of the following syllable.Liaison should not be confounded with chaining and elision phe-

nomena.The former concern normally pronounced conso-

nants[7].Liaisons without chaining can even be heard,par-ticularly in political debates[6].Liaison should also be dis-

tinguished from elision,which suppresses a vowel.More-

over,a limited number of consonants are used for liaison: /z/,/t/,/n/,//,/p/–the rank order is from highest to lowest for the frequency of occurrences.Yet,in the three cases, the consonant which terminates the?rst element generally

belongs to the initial syllable of the following word,which

may make the word boundary recognition more dif?cult. How and when is liaison made?We are here in a deli-cate?eld,and there is no consensus to answer this ques-tion.French liaisons have been studied in[4,7,6].Rather than assessing the accuracy of one of these

contributions,

we have chosen to compile them,in order to investigate rules describing so-called compulsory(see Tab.1),forbid-den(Tab.2)or optional liaisons(Tab.3)In the liaison rules we are going to examine the set of words likely to produce a liaison consonant is expressed,together with a speci?cation of the right context words;the“+”sign delimits the two. One of the contexts may be empty if there is no condition on the preceding or following words.Patterns thus may vary from open to one single word,but correspond most often to part-of-speech(PoS)tags with morpho-syntactic informa-tion.In the?rst7rules,for instance,there is a close gram-matical link between the words or parts-of-speech:within a noun phrase(see rules1and2)or within a verb phrase especially.As for rule8,it is an example of pattern limited to one word with unspeci?ed right context.In sum,liaison should be made in the contexts displayed in Tab.1.

3METHODOLOGY&EXPERIMENTAL

CONDITIONS

This study makes use of the B REF corpus[11]of read speech.The data contain66,500sentences read by120speakers.In the corresponding26,000word list,over25% have possible liaisons,which gives an idea of the phe-nomenon magnitude.

We de?ne the corpus(potential liaison corpus)as the set of word sequences of B REF with a potential liaison:a word with a liaison consonant followed by a word starting with a vowel or a glide–therefore,the term“potential”in this sense has nothing to do with“optional”liaisons de?ned in Section2.These word sequences are also referred to as li-aison contexts:we measured91,126occurrences of liaison contexts in the B REF corpus.

We then de?ne the corpus(observed liaison corpus)as the set of word sequences(liaison contexts)where a liaison is effectively observed.This corpus contains40,940liaison occurrences,which gives a global liaison rate of45%.

In the following,we will measure the relative weight of each rule in both the and the corpora.The?rst per-centage%indicates whether the rule under consideration is followed or not.The second percentage%re?ects the contribution or in other terms the relative importance of a given rule with respect to the general liaison phenomenon.

3.1Acoustic-phonetic alignment

The acoustic phone models are sets of continuous density hidden Markov models(HMMs)with Gaussian mixture. Context-dependent phone models are used to account for allophonic variation observed in different contexts.In or-der to determine the sequence of realised phones in a given utterance,a Markov chain is formed by concatenating the phone pronunciations associated with the words in the cor-responding orthographic transcription.This is then used to constrain the search space for the decoder,aligning the phones with the speech signal.If pronunciation variants are represented in the lexicon or added by phonological rules, a phone graph is constructed and aligned with the signal.In this case,the decoder will produce the most likely sequence of phones along with the time alignment.The LIMSI sys-tem was used,the accuracy of which was demonstrated by a series of evaluations[9].

3.2Pronunciation lexicon

The pronunciations and their variants were generated by a grapheme-to-phoneme converter,into which pronunciation variants were introduced.The program G RAPHON+[3]was used,whose word error rate on a30,000word running text is less than1%.For the purpose of this study,liaisons are allowed for all words ending with-s,-x,-z,-n,-d,-t,-r, -p.In our broad phonetic description,there is no mark for the“disjunctive h”which is assumed to prohibit rigth-to-left liaisons as in les héros(“the heroes”)vs les hommes (“the men”).We will discuss this further in4.2.

3.3Morpho-syntactic tagging

The morpho-syntactic information was produced by the C ORDIAL tagger retailed by Synapse Développement (Toulouse).It had to be aligned with the word tokens as used by the speech recognition(alignment)system.Now, though there is a straightforward correspondence for most items,tokenisation problems arise especially for

(e.g.a date like1984),acronyms and some compounds or idioms.Therefore,tokenisation had to be?tted to match

the output of the speech processing system.

The C ORDIAL tagset is very close to the one used in a series

of evaluation campaigns,inspired by M ULTEXT,G RACE

[1].In the current state-of-the-art,the error rate on words is about3%,which enables quite a reliable analysis. Looking at the PoS bigrams corresponding to the cor-pus(potential liaisons),the50most frequent PoS bigrams

account for about98.6%of the liaison corpus–in accord

with Zipf’s law.The15most frequent PoS sequences and their links with the liaison rules de?ned above are given in Tab.4.Some results on the occurrences of liaisons are also provided.But it is in next section that rule-speci?c experi-mental results will be presented.

4EXPERIMENTAL RESULTS

4.1Compulsory,forbidden and optional liaisons

For each of the rules described above,Tables5,6and7 give the number of occurrences in a potential liaison con-text,the percentage of occurrences with an observed liaison for the given rule(%),and the percentage these liaisons represent in the set of all observed liaisons(%).

We can observe that rules1-8(liaison rules)have all% rates over70%.Concerning rule3(which applies to18dif-ferent monosyllabic adverbs),this rate is observed only af-ter excluding the negation pas(“not”)from the rule-speci?c liaison contexts.Indeed(see Tables3and7),it appears that liaison after pas is rather optional(40%).The same40% rate can be observed for moins(“less”);and if94%of li-aisons are realised with très(“very”),a0%liaison can be measured for loin(“far”).Therefore,liaison seems to be far from compulsory.This strengthens Encrevé’s[6]classi-?cation which proposed this liaison as optional.

Rules4and5,which apply to pronouns such as en,on, ils,elles(“we,they”)–preceded by a dash in rule4–are

more respected than the previous one.So is rule6,in which forms ofêtre(“to be”)and avoir(“to have”)were included even if they were tagged as main verbs.

Likewise in rule10,these forms and semi-auxiliary verbs were excluded from main verbs.A constraint was also added to the right context,to avoid an intersection with rule 4.The status of the latter is moreover questionable,since an orthographic clue imposes liaison(here observed in over 99%of instances).Still,the rule remains violated whether the verb is in the singular or in the plural,in the following cases:font irruption(“burst in”),commencent aussi(“begin too”),vient alors(“comes then”).

Another no liaison rule is rule12,whose liaison rate can be compared to those of rules3and7.Rule12states that li-aison is prohibited after polysyllabic adverbs,conjunctions and prepositions.Although the overall liaison rate is very low(5.4%),liaison may be relatively frequent with some word sequences.Interstingly,the word sequence après avoir(“after having”)occurs with40%of actual liaison;in devant eux(“before them”),liaison is twice as frequent as no liaison.For devant elle(“before her”),liaison is even al-ways observed.Putative forbidden liaisons are all realised

in10%of occurrences or less.But again,this highlights that,beyond morpho-syntax,word identity exerts a strong in?uence.This is exempli?ed by the case of mais(“but”) in Tab.7(rule18vs13)and will be all the more obvious in next subsection.

4.2Focus on rule1(determiner+)

The?rst rule which states that,after a determiner,liaison is compulsory has been observed in95%,and these liaisons represent more than a third of all observed liaisons.This is the reason why we focus on this rule in Tables8and9:these tables provide breakdowns by PoS and subpatterns where liaison is generally omitted.Not surprisingly in Tab.8(see also Tab.4),the sequence determiner+noun accounts for a large number of liaisons.

Table8:Rule1breakdowns by PoS.(generally substantivised forms of verbs in the past participle).

When looking for the rule1pattern in the corpus, we observe that most of the liaisons which are not re-alised stem from words starting with a disjunctive h:e.g. hasard(“chance”),hautes(“high”),Hongrois(“Hungari-ans”).Also,liaison is often avoided with numerals(see Tab.8),loan words(especially those which begin with a glide)and acronyms–in particular those which start with a graphemic consonant(e.g.HLM,SVT),even though their spelled pronunciation starts with a phonemic vowel.

5DISCUSSION

The yielded results would merit checking at two levels: that of PoS tagging to verify if they ful?l the rules we re-quested,and that of speech,which requires hours of listen-ing.Only subsets of the data were listened to,so as to test the alignment.The?gures presented in the paper were not changed,since we cannot control whether correcting some errors would not introduce new ones.Nonetheless,the pre-sented study of French liaisons is to our knowledge the?rst automatic investigation of this phenomenon in a large spo-ken corpus.The measures obtained con?rm most of a priori linguistic predictions,and allow a ranking of the rules pro-posed in the literature.Most important is the rule concern-ing liaisons with determiners,which contributes to more than one third of all observed occurrences.Other important rules are the one for clitic pronouns,the one concerningêtre and avoir irrespective of their auxiliary or main verb status, and the rule for monosyllabic prepositions–each of these3 rules accounts for about10%of all observed liaisons.The obtained results favour the classi?cation of monosyllabic adverbs in the optional liaison category,partially in accor-dance with Encrevé’s viewpoint[6].

Liaison rates vary signi?cantly depending on word and word bigram identities.This con?rms that liaison is strongly linked to both syntactic and lexical levels[8].

A better knowledge of liaison production is of particular interest for descriptive phonetics,second language acquisi-tion and speech processing.An accurate modelling of liai-son phenomena may also contribute to a better structuring of the speech?ow.Words which are connected by a liai-son are acoustically marked as belonging to a larger scale unit:like prosody,liaison is an indicator of between-word juncture.This may open new?elds of investigation relating phonetic and semantic structures for speech understanding.

AN EXCITING JOB I have the greatest job in the world. I travel to unusual places and work alongside people from all over the world. Sometimes working outdoors, sometimes in an office, sometimes using scientific equipment and sometimes meeting local people and tourists, I am never bored. Although my job is occasionally dangerous, I don't mind because danger excites me and makes me feel alive. However, the most important thing about my job is that I help protect ordinary people from one of the most powerful forces on earth - the volcano. I was appointed as a volcanologist working for the Hawaiian V olcano Observatory (HVO) twenty years ago. My job is collecting information for a database about Mount Kilauea, which is one of the most active volcanoes in Hawaii. Having collected and evaluated the information, I help other scientists to predict where lava from the volcano will flow next and how fast. Our work has saved many lives because people in the path of the lava can be warned to leave their houses. Unfortunately, we cannot move their homes out of the way, and many houses have been covered with lava or burned to the ground. When boiling rock erupts from a volcano and crashes back to earth, it causes less damage than you might imagine. This is because no one lives near the top of Mount Kilauea, where the rocks fall. The lava that flows slowly like a wave down the mountain causes far more damage because it

黄自艺术歌曲钢琴伴奏及艺术成就

【摘要】黄自先生是我国杰出的音乐家，他以艺术歌曲的创作最为代表。而黄自先生特别强调了钢琴伴奏对于艺术歌曲组成的重要性。本文是以黄自先生创作的具有爱国主义和人道主义的艺术歌曲《天伦歌》为研究对象，通过对作品分析，归纳钢琴伴奏的弹奏方法与特点，并总结黄自先生的艺术成就与贡献。 【关键词】艺术歌曲；和声；伴奏织体；弹奏技巧 一、黄自艺术歌曲《天伦歌》的分析 （一）《天伦歌》的人文及创作背景。黄自的艺术歌曲《天伦歌》是一首具有教育意义和人道主义精神的作品。同时，它也具有民族性的特点。这首作品是根据联华公司的影片《天伦》而创作的主题曲，也是我国近代音乐史上第一首为电影谱写的艺术歌曲。作品创作于我国政治动荡、经济不稳定的30年代，这个时期，这种文化思潮冲击着我国各个领域，连音乐艺术领域也未幸免――以《毛毛雨》为代表的黄色歌曲流传广泛，对人民大众，尤其是青少年的不良影响极其深刻，黄自为此担忧，创作了大量艺术修养和文化水平较高的艺术歌曲。《天伦歌》就是在这样的历史背景下创作的，作品以孤儿失去亲人的苦痛为起点，发展到人民的发愤图强，最后升华到博爱、奋起的民族志向，对青少年的爱国主义教育有着重要的影响。 （二）《天伦歌》曲式与和声。《天伦歌》是并列三部曲式，为a+b+c，最后扩充并达到全曲的高潮。作品中引子和coda所使用的音乐材料相同，前后呼应，合头合尾。这首艺术歌曲结构规整，乐句进行的较为清晰，所使用的节拍韵律符合歌词的特点，如三连音紧密连接，为突出歌词中号召的力量等。 和声上，充分体现了中西方作曲技法融合的创作特性。使用了很多七和弦。其中，一部分是西方的和声，一部分是将我国传统的五声调式中的五个音纵向的结合，构成五声性和弦。与前两首作品相比，《天伦歌》的民族性因素增强，这也与它本身的歌词内容和要弘扬的爱国主义精神相对应。 （三）《天伦歌》的伴奏织体分析。《天伦歌》的前奏使用了a段进唱的旋律发展而来的，具有五声调性特点，增添了民族性的色彩。在作品的第10小节转调入近关系调，调性的转换使歌曲增添抒情的情绪。这时的伴奏加强和弦力度，采用切分节奏，节拍重音突出，与a段形成强弱的明显对比，突出悲壮情绪。 c段的伴奏采用进行曲的风格，右手以和弦为主，表现铿锵有力的进行。右手为上行进行，把全曲推向最高潮。左手仍以柱式和弦为主，保持节奏稳定。在作品的扩展乐段，左手的节拍低音上行与右手的八度和弦与音程对应，推动音乐朝向宏伟、壮丽的方向进行。coda 处，与引子材料相同，首尾呼应。 二、《天伦歌》实践研究 《天伦歌》是具有很强民族性因素的作品。所谓民族性，体现在所使用的五声性和声、传统歌词韵律以及歌曲段落发展等方面上。 作品的整个发展过程可以用伤感――悲壮――兴奋――宏达四个过程来表述。在钢琴伴奏弹奏的时候，要以演唱者的歌唱状态为中心，选择合适的伴奏音量、音色和音质来配合，做到对演唱者的演唱同步，并起到连接、补充、修饰等辅助作用。 作品分为三段，即a+b+c+扩充段落。第一段以五声音阶的进行为主，表现儿童失去父母的悲伤和痛苦，前奏进入时要弹奏的使用稍凄楚的音色，左手低音重复进行，在弹奏完第一个低音后，要迅速的找到下一个跨音区的音符；右手弹奏的要有棱角，在前奏结束的时候第四小节的t方向的延音处，要给演唱者留有准备。演唱者进入后，左手整体的踏板使用的要连贯。随着作品发展，伴奏与旋律声部出现轮唱的形式，要弹奏的流动性强，稍突出一些。后以mf力度出现的具有转调性质的琶音奏法，要弹奏的如流水般连贯。在重复段落，即“小

写作中，不可忽略的是钢琴伴奏织体的作用，因此作曲家们通常都以丰富的伴奏织体来烘托歌曲的意境，铺垫音乐背景，增强音乐感染力。和声织体，复调织体都在许多作品中使用，较为常见的是综合织体。这些不同的伴奏织体的歌曲，极大限度的发挥了钢琴的艺术表现力，起到了渲染歌曲氛围，揭示内心情感，塑造歌曲背景的重要作用。钢琴伴奏成为整体乐思不可缺少的部分。优秀的钢琴伴奏织体，对发掘歌曲内涵，表现音乐形象，构架诗词与音乐之间的桥梁等方面具有很大的意义。在不断发展和探索中，也将许多伴奏织体使用得非常娴熟精确。 二、青主艺术歌曲《我住长江头》中钢琴伴奏的特点 《我住长江头》原词模仿民歌风格，抒写一个女子怀念其爱人的深情。青主以清新悠远的音乐体现了原词的意境，而又别有寄寓。歌调悠长，但有别于民间的山歌小曲；句尾经常出现下行或向上的拖腔，听起来更接近于吟哦古诗的意味，却又比吟诗更具激情。钢琴伴奏以江水般流动的音型贯穿全曲，衬托着气息宽广的歌唱，象征着绵绵不断的情思。由于运用了自然调式的旋律与和声，显得自由舒畅，富于浪漫气息，并具有民族风味。最有新意的是，歌曲突破了“卜算子”词牌双调上、下两阕一般应取平行反复结构的惯例，而把下阕单独反复了三次，并且一次比一次激动，最后在全曲的高音区以ff结束。这样的处理突出了思念之情的真切和执著，并具有单纯的情歌所没有的昂奋力量。这是因为作者当年是大革命的参加者，正被反动派通缉，才不得不以破格的音乐处理，假借古代的

选修6英语课本原文文档

高中英语选修 6 Unit 1 A SHORT HISTORY OF WESTERN PAINTING Art is influenced by the customs and faith of a people. Styles in Western art have changed many times. As there are so many different styles of Western art, it would be impossible to describe all of them in such a short text. Consequently, this text will describe only the most important ones. Starting from the sixth century AD. The Middle Ages(5th to the 15th century AD) During the Middle Ages, the main aim of painters was to represent religious themes. A conventional artistof this period was not interested in showing nature and people as they really were. A typical picture at this time was full of religious symbols, which created a feeling of respect and love for God. But it was evident that ideas were changing in the 13th century when painters like Giotto di Bondone began to paint religious scenes in a more realistic way. The Renaissance(15th to 16th century) During the Renaissance, new ideas and values gradually replaced those held in the Middle Ages. People began to concentrate less on

英语选修六课文翻译 第五单元

英语选修六课文翻译第五单元 reading An exciting job I have the greatest job in the world. travel to unusual places and work alongside people from all over the world sometimes working outdoors sometimes in an office sometimes using scientific equipment and sometimes meeting local people and tourists I am never bored although my job is occasionally dangerous I don't mind because danger excites me and makes me feel alive However the most important thing about my job is that I heIp protect ordinary people from one of the most powerful forces on earth-the volcano. I was appointed as a volcanologist working for the Hawaiian Volcano Observatory (HVO) twenty years ago My job is collecting information for a database about Mount KiLauea which is one of the most active volcanoes in Hawaii Having collected and evaluated the information I help oyher scientists to predict where lava from the path of the lava can be warned to leave their houses Unfortunately we cannot move their homes out of the way and many houses have been covered with lava or burned to the ground. When boiling rock erupts from a volcano and crashes back to earth, it causes less damage than you might imagine. This is because no one lives near the top of Mount Kilauea, where the rocks fall. The lava that flows slowly like a wave down the mountain causes far more damage because it buries everything in its path under the molten rock. However, the eruption itself is really exciting to watch and I shall never forget my first sight of one. It was in the second week after I arrived in Hawaii. Having worked hard all day, I went to bed early. I was fast asleep when suddenly my bed began shaking and I heard a strange sound, like a railway train passing my window. Having experienced quite a few earthquakes in Hawaii already, I didn't take much notice. I was about to go back to sleep when suddenly my bedroom became as bright as day. I ran out of the house into the back garden where I could see Mount Kilauea in the distance. There had been an eruption from the side of the mountain and red hot lava was fountaining hundreds of metres into the air. It was an absolutely fantastic sight. The day after this eruption I was lucky enough to have a much closer look at it. Two other scientists and I were driven up the mountain and dropped as close as possible to the crater that had been formed duing the eruption. Having earlier collected special clothes from the observatory, we put them on before we went any closer. All three of us looked like spacemen. We had white protective suits that covered our whole body, helmets,big boots and special gloves. It was not easy to walk in these suits, but we slowly made our way to the edge of the crater and looked down into the red, boiling centre. The other two climbed down into the crater to collect some lava for later study, but this being my first experience, I stayed at the top and watched them.
