There's a couple of iOS apps that support Sichuanese TTS (text-to-speech):

  • 川话达人
  • 语音合成助手

From what I can tell it's all from a company called 讯飞, but I'm not totally sure.

Is there an open source Sichuanese TTS available?


An offline Sichuanese TTS that doesn't need to download the audio each time?

  • An open source TTS, offline, and for a Chinese dialect used by only 8 percent of the total population? I'm not sure. Even open source TTS for standard Chinese is rare, if it exists. Oct 19 '15 at 8:27
  • Whether it can handle Sichuanese mainly depend on the data of the TTS, not the code.

You're right about the company. It's full name is 科大讯飞. 科大is short for 中国科学技术大学(University of Science and Technology of China),my Alma mater!--this company is founded by several alumni in cooperation with the university.

TTS is not difficult for 科大讯飞, and they put their effort more on speech-to-text engine. But they have open source packages for both TTS and STT, and a whole bunch of other cool stuff. Actually, they have been there at least since 2014. You could find them here (all-Chinese site): http://www.xfyun.cn/sdk/dispatcher Their TTS and STT support A LOT of dialects.

Alternatively, there is a Chinese TTS on Github: https://github.com/yantze/vim-tts It also supports a lot of dialects, including Sichuanese.


No, there is no such open-source Sichuanese TTS available so far.


讯飞 (short for 科大讯飞) is a leading tech company in speech synthesis and recognition. An online-demo for Sichuanese TTS is demonstrated on their website. In addition, they have provided an offline TTS SDK, you may have a try.
