matt-oakes / pyttsx4

Offline Text To Speech synthesis for python

the code is mostly from pyttsx3.

only because the repo pyttsx3 does not update for years and some new feature i want is not here, i cloned this repo.

the changelog:

1. add memory support for sapi5
2. add memory support for espeak(espeak is not tested). eg:

b = BytesIO()
engine.save_to_file('i am Hello World', b)
engine.runAndWait()

3. fix VoiceAge key error

4. fix for sapi save_to_file when it run on machine without outputsream device.

5. fix save_to_file does not work on mac os ventura error. --3.0.6

6. add pitch support for sapi5(not tested yet). --3.0.8

NOTE:

if save_to_file with BytesIO, there is no wav header in the BytesIO. the format of the bytes data is that 2-bytes = one sample.

if you want to add a header, the format of the data is: 1-channel. 2-bytes of sample width. 22050-framerate.

how to add a wav header in memory:Jiangshan00001#2

#TBD: add support for TTS.

how to use:

install:

pip install pyttsx4

use:

import pyttsx4
engine = pyttsx4.init()

the other usage is the same as the pyttsx3
