I am designing an English dictionary-like app and using OpenEars TTS for pronunciation but the voice quality is not so good. Any suggestion to improve its sound quality?

  • I guess best place to ask this would be the forum on their site. But isn't their TTS ment more of a tool that helps their speech recognition engine to do it's work. I don't think it is ment to be used the way you're trying to. – Rok Jarc Aug 21 '12 at 16:37
  • What is your recommendation for TTS in iOS? – DavidNg Aug 21 '12 at 21:16
  • Yuji provided a link to private API and to another question with many suggestions [here](http://stackoverflow.com/a/9939686/653513). Didn't try any of those but the accepted answer seems promising. – Rok Jarc Aug 22 '12 at 07:28
  • "But isn't their TTS ment more of a tool that helps their speech recognition engine to do it's work." Nah, it's intended to be used just as DavidNg is using it (OpenEars has a separate TTS class from its speech recognition class), but not everyone likes the Flite voices. DavidNg, did you try the 16-bit slt voice? Most developers seem to like it best out of the Flite voices. – Halle Aug 28 '12 at 19:35
  • @Halle: what is "16-bit slt voice" ? – DavidNg Aug 28 '12 at 20:17
  • There are 8 voices in OpenEars' FliteController class, have you tried them all? The 16-bit slt voice is the one selected with the string @"cmu_us_slt" (not @"cmu_us_slt8k"). If you have more questions for me, do me a favor and bring them over to the OpenEars forum. – Halle Aug 28 '12 at 20:20
  • @Halle: I see, OK, I will change to this setting to see how good it is – DavidNg Aug 28 '12 at 20:24
  • You can download different voices here .. https://bitbucket.org/Politepix/openearsextras/src – John Paul Manoza Nov 28 '13 at 01:45
  • Why not use native ios siri tts? – PressingOnAlways Apr 17 '14 at 18:09

If you are supporting iOS7 and above, you can consider using AVSpeechSynthesizer.

What you can do is contact them directly and state your problem. Here is the link to their contact site: http://www.politepix.com/contact/

The best way to get your question answered is in their forums and here is the link for that: http://www.politepix.com/forums/forum/openearsforum/

They also have a private support service but that will cost you some money but here is the link for that: http://www.politepix.com/shop/openears-support-incident/
