Slow TTS when long text

[dannyshmueli]

Hi Halle,

I’v playing with OpenEars for few days now and i really like it :)

One issue though (i dont know if it’s OpenEars specific): when i try to TTS large text (say from an article) it takes it a long time until it starts playing it.

Small text: 1.5 seconds

Large text: 74 seconds

The long wait is due to:

cst_wave *speechwaveform = flite_text_to_wave(statementToSay,voice);

 in FliteController.h ,I added NSLog output of the time it takes this call to finish.

Is there any way of speeding this up?

Thanks,

Danny

Welcome Danny,

I’m glad to hear you’re enjoying OpenEars. The fact that all text is rendered at once and then played when it’s all ready is a limitation of FliteController, but NeatSpeech (a paid plugin for OpenEars here: https://www.politepix.com/neatspeech) was created in order to speed up speech by streaming long speech in segments instead of first rendering everything and then playing, so you might want to give its demo a try and see if it helps with your requirements.
