The only reason it sounds good with vocoders is because the codec parameters are in fact synthesizer parameters that don't have a direct connection with the signal.

...ng the low quality speech. Speech sounds terrible at 1.01X faster, and it sounds excellent at normal speed (1.0X). So, the main problem is something that breaks with any change in frame size in the decoder. Any idea what that might be?

Hi. I'm Bill Cox, and I volunteer a bit for the Vinux project, which is Linux for people with vision impairments. Most blind users use a closed-source speech synthesis tool called voxin, as it's very easy to understand at high speed. I would like to make TTS synthesizers based on large recorded vocabularies of actual speech, but to make it useful for the blind, I need to be able to

I was able to easily hack in an option to play back at different speeds. For example, using "speexdec --speed 2.0 file.enc file.wav" plays back encoded file.enc at 2X speed. What I did was divide st->frameSize and st->subFrameSize by the speedup, and added a SPEEX_SET_SPEED decoder control for the nb_celp decoder. This produced speech that was 2X faster than the original.

In a simple webapp containing users and user icons, what''s the right way to use ActiveRecord to store these objects and then designate a single ''primary'' icon for each user, given: - a set of users. - for each user, zero or more icons they''ve uploaded (tied to their account). - for each user, zero or one icon from their set of uploaded icons designated as
