search for: diphones

I am using speex for encoding and decoding speech files in a speech synthesis program. I am using concatenative approach for speech synthesis using diphones (small speech chunks) as basic unit. Now in my application, the order of diphones to be joined after decoding is determined at runtime. Therefore I have to encode each diphone independent of others. I find out that when I encode diphones in order of their concatenation with out reinitializing...

Hi, Andras, Thanks for the comments. Yes, I am aware of those issues. I probably should have been more accurate on my usage of terms. Actually in my project, the unit collection is a mixture of diphones and words. However seems to me, these synthesizer specific issue is irrelevant to my question about speex. As you said, i merely use speex as storage methods. All I ask for is to get the samples as close to original recording as possible after encoding and decoding. Blending, cross fading,...

Ok, let me first explain why 5ms matters, even they are 0's, in my particular application. I am working on a speech synthesis system. The basic idea is concatenating pre-recorded phonemes or words into longer sentences. So any missing or extra samples, even it is as short as 5~10ms, cause very noticeable discontinuities. I want to use speex to compress/decompress those pre-recorded

...Most flexible (unlimited vocabulary), unit (e.g. "phoneme") concatenation speech synthesizers therefore use some strategy to blend the pieces of speech together, usually both in pitch and in phoneme quality. One very conceptually simple and therefore popular approach is storing "diphones" - phoneme transitions: e.g. the second half of "a" and the first half of "p" from the hypothetical word "apa". Since phonemes usually tend to reach their "most recognizable" state in the "middle", cutting and splicing them together around t...

Hi, Is there IAX client in Applet JAVA which can be embeded in a web page ? Best regards Rattana -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-users/attachments/20031208/c388ef61/attachment.htm
