I would love to see a > 802.11 phone like that, complete with a tiny price. :)That's interesting. Mostly because I'm a hobbyist Gameboy programmer, and the AGB is an Arm7TDMI/16.78mHz. How big are speex "chunks?" Are we talking about groups of seconds, or fractions of seconds? If they're small enough, that might make Speex a good solution for speech generation, given a large enough fragment dictionary... hrm. --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'speex-dev-request@xiph.org' containing only the word 'unsubscribe' in the body.

Hi, I might have written to this mailing list previously about this but I've been experiencing some mailing problems so I write this again. First of all, thanks Jean-Marc Valin for your continued efforts on speex. I must say that I am very impressed with Speex and further more the innovative features recently added in 1.1. They have worked great for me. Question 1) What is the return value from speex_preprocess good for? It's called "vad" in the denoise sample. It seems always to be = 1. Question 2) While comparing Speex with GSM 06.10. It struck me that Speex is pretty CPU intense compared to GSM 06.10. Are there any plans or (even) possibilities of optimizing Speex? In my sample program for Win32 compiled with MSVS.NET. Speex loads about 7 % CPU in Narrow mode, compared to GSM 06.10 which loads approx. 0,5 to 1.0 %. I am not sure if the CPU usage is reliable in any way as a benchmark. <p>//Best Regards, Jonas Tärnström, Sweden. <p><p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'speex-dev-request@xiph.org' containing only the word 'unsubscribe' in the body.

However, you can compress single frames efficiently using Speex, because Speex makes use of the previous frame(s) when encoding a frame. Jean-Marc -- Jean-Marc Valin, M.Sc.A., ing. jr.
