Charsiu: A transformer-based phonetic aligner [arXiv]
- 2.10.2022. We release phone- and word-level alignments for 860k utterances from the English subset of Common Voice. Check out this link.
- 1.31.2022. We release phone- and word-level alignments for over a million Mandarin utterances. Check out this link.
- 1.26.2022. Word alignment functionality has been added to
charsiu_forced_aligner.
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)
The aligner is under active development. New functions, new languages and detailed documentation will be added soon! Give us a star if you like our project!
Fun fact: Char Siu is one of the most representative dishes of Cantonese cuisine 🍲 (see wiki).

[!NEW] A step-by-step tutorial for linguists:
You can directly run our model in the cloud via Google Colab!
- Forced alignment:
- Textless alignment:
git clone https://github.com/lingjzhu/charsiu
cd charsiu
from Charsiu import charsiu_forced_aligner
# if there are errors importing, uncomment the following lines and add path to charsiu

This tool is a beta version and is still under active development. It may have bugs and quirks, alongside the difficulties and provisos which are described throughout the documentation. This tool is distributed under MIT license. Please see license for details.
By using this tool, you acknowledge:
-
That you understand that this tool does not produce perfect camera-ready data, and that all results should be hand-checked for sanity's sake, or at the very least, noise should be taken into account.
-
That you understand that this tool is a work in progress which may contain bugs. Future versions will be released, and bug fixes (and additions) will not necessarily be advertised.
-
That this tool may break with future updates of the various dependencies, and that the authors are not required to repair the package when that happens.
-
That you understand that the authors are not required or necessarily available to fix bugs which are encountered (although you're welcome to submit bug reports to Jian Zhu (lingjzhu@umich.edu), if needed), nor to modify the tool to your needs.
-
That you will acknowledge the authors of the tool if you use, modify, fork, or re-use the code in your future work.
-
That rather than re-distributing this tool to other researchers, you will instead advise them to download the latest version from the website.
... and, most importantly:
- That neither the authors, our collaborators, nor the the University of Michigan or any related universities on the whole, are responsible for the results obtained from the proper or improper usage of the tool, and that the tool is provided as-is, as a service to our fellow linguists.
All that said, thanks for using our tool, and we hope it works wonderfully for you!
