Liason in French

Question

Liason in French

alt131 opened this issue 3 years ago · comments

In French sometimes two words sound like one
DEBUG:larynx:Words for 'oui, c'est un': ['oui', ',', "c'est", 'un']
DEBUG:larynx:Phonemes for 'c'est un': ['#', 's', 'e', 't', '#', 'œ̃', '#', '‖', '‖']
't' was lost in the output wav and phonemes should be something like this
DEBUG:larynx:Phonemes for 'c'est un': ['#', 's', 'e', 't', 'œ̃', '#', '‖', '‖']

DEBUG:larynx:Words for 'ce n'est pas un': ['ce', "n'est", 'pas', 'un']
DEBUG:larynx:Phonemes for 'ce n'est pas un': ['#', 's', 'e', 'ə', '#', 'n', 'ɛ', '#', 'p', 'a', '#', 'œ̃', '#', '‖', '‖']
the output wav was OK ('z' was added) but I think phonemes should be something like this
DEBUG:larynx:Phonemes for 'ce n'est pas un': ['#', 's', 'e', 'ə', '#', 'n', 'ɛ', '#', 'p', 'a', 'z', 'œ̃', '#', '‖', '‖']

Liason looks like it's going to be fairly complex to implement correctly. I'm leaving this link here for future me: https://github.com/juliacarbajal/french_phonologizer/blob/master/phonologize.py

alt131 · Answer 2 · Tue Apr 13 2021 03:48:00 GMT+0800 (China Standard Time)

I can suggest this algorithm.

If last symbol of first word is 's', 'x', 'z', 't', 'd' and first symbol of second word is h or any vowel
If last symbol of first word is consonant + apostrophe and first symbol of second word is h or any vowel
then if the last consonant in 1st word is pronounced then just delete pause between words
if last consonant in 1st word is NOT pronounced then change pause between words on 'z' for 's', 'x', 'z' and on 't' for 't', 'd'.
I think it covers most cases.

alt131 · Answer 3 · Tue Apr 13 2021 03:51:06 GMT+0800 (China Standard Time)

Also I think it's not all examples by link is correct in modern French.
For example (from your learning French dataset), "any instances of après that are not part of après-midi"
Cyrus Smith et Gédéon Spilett, après être << liason
C’est le mot du professeur, qui, après avoir << liason

but I'm not a native French speaker.

Tom Darboux · Answer 4 · Tue Apr 13 2021 07:45:41 GMT+0800 (China Standard Time)

I agree liason in french is important, it helps a lot to understand the speaker and larynx doesn't make it.
At this late hour, I will not pick a solution. It fairly complex to know when we should make liaison or not (in fact it's more a feeling than a rule that I apply).
I found this algorithm yesterday, with two function check_liaison which verify if we should to do a liason between two words. And liaison which apply the liaison.

For french speaker, here is an article talking when we should do the liason or not:
https://www.francaisauthentique.com/quand-faire-la-liaison-en-francais/

Tomorrow I could make a summary in english.

alt131 · Answer 6 · Tue Apr 13 2021 20:39:35 GMT+0800 (China Standard Time)

@tjiho, I don't think it's possible to make an one universal solution. For example, in your article he wrote you shouldn't use a liason for phrases like “des haricots” (last 's' and first 'h') but if you check siwis dataset in sentence "Voilà donc de quoi dépendent les destins des hommes !" she used a liason for "des_hommes" and as I know it's a standard pronunciation. Maybe it depends from region where man/woman lives but even in most known self-study guide Mauger "Course de Lange et de Civilisation Francaises" they used the liason in that case (see the page 4: [dezom]).

Tom Darboux · Answer 7 · Wed Apr 14 2021 00:18:39 GMT+0800 (China Standard Time)

@alt131 About liason with h I searched on internet and I found this: http://www.languefrancaise.net/forum/viewtopic.php?id=180
It say (in summary) that there is not liason with word beginning with a h non latin (Germanic or Greek). There is a list of those (~200), i will search it and publish it when I'll have the list.
It's very ugly to say des_haies [dezɛ]. And you're right it should say des_hommes [dezom].

Tom Darboux · Answer 8 · Wed Apr 14 2021 00:43:58 GMT+0800 (China Standard Time)

For french speaker, here is an article talking when we should do the liason or not:
https://www.francaisauthentique.com/quand-faire-la-liaison-en-francais/

Tomorrow I could make a summary in english.

So it lists some rules:

you should do a liaison only it the first word ends in a consonant and the second begins with a vowel.
determinant + noun : liason
pronoun + verb : liason
adjective + noun : liason
there is a list of typical expression to know for which you should do a liason (todo: find this list).
noun + adjective: no liason
after et: no liason (else it sounds like est)
after the verb être and avoir liason is optional (it sounds more formal with the liason) - we could simplify after a verb no liason
if the second word begin with a h aspiré (non latin words) : no liason (todo: find the list)
if the second word begin with a h muet (latin words): liason

alt131 · Answer 9 · Wed Apr 14 2021 00:56:52 GMT+0800 (China Standard Time)

@synesthesiam, did you define a part of speech of word in gruut?
@tjiho, ok, it's a good list, but do you understand it's not so easy to detect a part of speech of word in text?

Tom Darboux · Answer 10 · Wed Apr 14 2021 01:07:41 GMT+0800 (China Standard Time)

@tjiho, ok, it's a good list, but do you understand it's not so easy to detect a part of speech of word in text?

@alt131 yes i understand it 😅 It will be a big improvement to have correct liason.

alt131 · Answer 11 · Wed Apr 14 2021 01:16:12 GMT+0800 (China Standard Time)

@tjiho, I doubt what gruut has a syntactical analyzer.
I suggest to use my algorithm above and add there some exceptions like 'et' for first word and 'à', 'il', 'elle' etc for second word. It covers 95-98% cases for TTS and STT and there is 3 sentences on Python I believe.

alt131 · Answer 12 · Wed Apr 14 2021 01:21:15 GMT+0800 (China Standard Time)

And I also believe it's not a big problem if we'll not add a liason for "un_ami" etc, at least for speech-to-text neuro net.

A bit more 😇 There are 573 words. That's nice, so we have all the words with a h aspiré .

Can you give some example(s)?

Michael Hansen · Answer 16 · Wed Apr 14 2021 02:20:45 GMT+0800 (China Standard Time)

Gruut can do syntax analysis using python-crfsuite. I trained a model for French today on the French Universal Dependencies treebank, and it seems to work quite well.

Here's the result of my first attempt: https://drive.google.com/drive/folders/1a232BIJ_gTfm3wHEKr0F86K8BkepQYay?usp=sharing

I took my example sentences from here and implemented just these few rules (for now):

"et" = no liason
determiner -> anything = liason
pronoun -> verb, liason
preposition or très -> noun, liason

adjective + noun : liason
I believe there are adjectives like grand, petit, gros, long, beaux, bel
It's possible to add them to a first word exception.

It apply to this kind of adjectives (qualificatif) : un petit_ami
But also to:

possessive adjectives, mon, ma, mes, ton, ta, tes, etc... : mon_amant
relative adjectives, Lequel, duquel, auquel, laquelle, Lesquels, desquels, auxquels, Lesquelles, desquelles, auxquelles : Lesquelles_avocats.
And numeral adjective (numbers): deux_amants
other adjective are in fact determinant

there is a list of typical expression to know for which you should do a liason (todo: find this list).
Can you give some example(s)?

Sure, the article talks about some expressions:
tout_à l’heure
c’est_à dire
plus_ou moins
peut_être

@synesthesiam, I like it but "Je vis en Amérique." Phonems is correct but the pronunciation is not.
'Ton excellent vin.' also has a problem with pronunciation. I think they both have relation with #5.

You have at least 2 bugs in French models.
First bug. Current NNs were trained without the liason.
Second bug. To compeтsate first bug you added # in liason.
I think you need to delete # in liason and train swiss model for test. I believe the result will be better quality and more accurate
And bug #5 still exists for example for 'livre' or 'homme' phonemes are OK but pronunciation is not (inside a word)

Haven't updated the Docker images yet. I had to roll back to push a different fix.

The ValueError you got is likely from leaving the --csv command-line argument on while passing in sentences without an id field (like id|text).

The ValueError you got is likely from leaving the --csv command-line argument on while passing in sentences without an id field (like id|text).

No, it's because in " l`arbre" used no standard apostrophe. If I change it on standard ', then it works OK.

Just wanted to mention:

Phonemes for 'Michel est un grand ami.': ['#', 'm', 'i', 'ʃ', 'ɛ', 'l', '#', 'ɛ', '#', 'œ̃', 'n', '#', 'ɡ', 'ʁ', 'ɑ̃', 't', 'a', 'm', 'i', '#', '‖', '‖']

On this pronunciation sample, I hear a D-sound rather than the expected T-sound: est “D”un grand instead of est “T”un grand.
