TTS in calibre v7.18

jackie_w · Yesterday, 04:40 PM

With the introduction of the new Piper speech engine in v7.18 my 'TTS to MP3' plugin no longer works. It fails on

Code:

from calibre_extensions.winsapi import ISpVoice

I don't see any sign of winsapi anymore. Is ISpVoice gone for good? If so does the Piper speech engine have an equivalent Python class with similar methods, specifically .create_recording_wav()?

Yes, the entire old TTS infrastructure is gone. No, there is currently no such method for piper but you can implement it yourself fairly easily, piper is a standalone executable bundled with calibre, you can run piper.exe --help to learn how to use it to convert text to speech.

You can also access the windows/macos/linux speech engines via the Qt Text to Speech classes (this is what calibre uses now for TTS with system speech engines).

Finally I could add a method to the new TTSEngine classes in calibre to generate wav output, however, since calibre itself has no use for this, it's not a priority for me.
