This fixed it. Thanks!

Released preview 7.20.100 with a new tool in the editor to embed Piper TTS based audio overlays into EPUB 3 files. You can even markup different parts of the text to be read by different voices and it handles different languages automatically.

There's something not working for me, although the audio is correctly created and embedded in the EPUB. I get "Could not load the audio file".

I've attached some screencaps and the trimmed epub I've used to test this new feature.

Also, I've added three distinct voices to the first paragraphs, but the audio created is all Ryan's, is that correct? Maybe I'm doing something incorrectly.

Yeah looks like on windows, Qt WebEngine is unable to play m4a files. Probably missing codecs in the webengine bundle. Sigh. I forgot to test that. Stupid software patents. You should still be able to play it using the content server viewer in a browser.

I'll look at why the voice is not changing later.

ah, yes. On the content server in a browser it's working fine, I just checked.

(amazing feature BTW, one which people with vision impairment will certainly appreciate)

This should fix the voice changes not happening:

wheee, now I see the markup working, third voice in the attached audio is my custom "lessac" (GlaDOS)

later i'm going to do more tests, but I had chosen Alan as default voice.

yet the book seems to default to the first voice I had used in the markup (cory).

[kovidgoyal]

Doesnt happen for me. I didnt choose a default voice for english so it defaulted to libritts. The non cory/ryan text was read in libritts as expected.

Released another preview: Major features: Viewer can now play m4a audio files and in dark mode the scrollbar has improved contrast. Lots of minor bug fixes as well.

Thanks a lot for the new scrollbar for dark mode.

Now, about the audio overlay. I noticed two things:

1) Some short sentences (one or two words) tend to get a wrong audio markup. Example:

HTML:

<p class="texto"><span id="cttsw-33">– Claro. </span><span id="cttsw-34">Eu tenho passagem pela prisão, então se algum crime tiver sido cometido, eu devo ser a responsável.</span></p>

SMIL:

<par id="par-33">
        <text src="74.xhtml#cttsw-33"/>
        <audio src="74.xhtml.m4a" clipBegin="00:01:28.61" clipEnd="00:01:28.549"/>
</par>

Notice the 'clipBegin' and 'clipEnd' timings. Because of this, the sentence is not highlighted when reading aloud in the viewer (and stops highlighting altogether in ADE).

2) In the OPF, the 'media:duration' property is only set for the last smil file. The read aloud works just fine in calibre, but I don't know if this could cause an error on other reading devices.

1) Some of the negative durations were corrected, but not all. I'm still getting this error for some short sentences.

2) The 'time:duration' property is now set for every smil file and for the total duration (although EPUBCheck still complains that the total duration doesn't add up for the sum of all clips' durations; if I remember correctly, the tolerance is 1 sec.)
