pyttsx4 3.0.11

Text to Speech (TTS) library for Python 3. Works without internet connection or delay. Supports multiple TTS engines, including Sapi5, nsss, and espeak.

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

7. fix nsss engine: Import super from objc to fix AttributeError by @matt-oakes.

8. add tts support: deep-learning text to voice backend:

just say:

engine = pyttsx4.init('coqui_ai_tts')
engine.say('this is an english text to voice test.')
engine.runAndWait()

cloning someones voice:

engine = pyttsx4.init('coqui_ai_tts')
engine.setProperty('speaker_wav', './someones_voice.wav')

engine.say('this is an english text to voice test.')
engine.runAndWait()

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:https://github.com/Jiangshan00001/pyttsx4/issues/2

how to use:

install:

pip install pyttsx4

use:

import pyttsx4
engine = pyttsx4.init()

the other usage is the same as the pyttsx3
