Overview

Charsiu: A transformer-based phonetic aligner [arXiv]

Note. This is a preview version. The aligner is under active development. New functions, new languages and detailed documentation will be added soon!

Intro

Charsiu is a phonetic alignment tool, which can:

recognise phonemes in a given audio file
perform forced alignment using phone transcriptions created in the previous step or provided by the user.
directly predict the phone-to-audio alignment from audio (text-independent alignment)

Fun fact: Char Siu is one of the most representative dishes of Cantonese cuisine 🍲 (see wiki).

Tutorial (In progress)

You can directly run our model in the cloud via Google Colab!

TextGrid file isn't according to spec

Could you check if .textgrid file produced is according to spec?

i'm using this https://github.com/nltk/nltk_contrib/blob/95d1806e2f4e89e960b76a685b1fba2eaa7d5142/nltk_contrib/textgrid.py to test generated textgrid files.

How do we use the pretrained attention aligner?

Hi, I find that getting a pretrained predictive aligner (aligner='charsiu/en_w2v2_fc_10ms') to work with librispeech seems straightforward. However, I'm unable to get the attention aligner working - how do I go about initializing the aligner and how do I get the corresponding bert config to go with it? Keeps throwing an error for the same.

Bug in phoneme to word conversion -- duplicate words

Something seems to be not right with how SIL is used in the word transcriptions.

This is the first example in the LibriSpeech Test set.

Here is the true transcript:

HE BEGAN A CONFUSED COMPLAINT AGAINST THE WIZARD WHO HAD VANISHED BEHIND THE CURTAIN ON THE LEFT

Here is the forced aligned word transcript:

I suspect this may indicate a general problem with the phoneme to word conversion.

Can't currently support long audio ?

“Charsiu works the best when your files are shorter than 15 ms. Test whether your files are longer than 15ms”

I saw this hint in the description and tested it.

Forcing alignment of long audio, the following error message will appear:

Traceback (most recent call last): File "test.py", line 31, in <module> charsiu.align(audio=audio, text=text) File "E:\***/python/charsiu/charsiu/src\Charsiu.py", line 157, in align pred_words = self.charsiu_processor.align_words(pred_phones,phones,words) File "E:\***/python/charsiu/charsiu/src\processors.py", line 417, in align_words word_dur.append((dur,words_rep[count])) #((start,end,phone),word) IndexError: list index out of range
