Hello,
I am JungAh Lee of Nuance communications.
I have a question about the license part described in http://www.speex.org/fsos/.
Does it mean I don't need to provide the application source code, though I modify the speex source code or use a part of it within my program?
Regards,
JungAh

Hi All,
I am trying to use Speex + PyAudio to convert voice to text using Google
Speech API. I downloaded PyAudio Source, PortAudio and Speex and installed
portaudio, followed by pyaudio with static link and then speex also I
installed.
I am able to import both speex and pyaudio into python fine. But when I
call these functions:
e = speex.Encoder()
e.initialize(speex.SPEEX_MODEID_UWB)
I get a segmentation fault.
speex shared object am linking points to libspeex.so.1
Any idea why this is happening? Any help appreciated
Thanks
Mani

HI:
Nowadays ,I am developing an IP phone on ARM platform , and the echo occur while talking.
I active the speex ec filter ,but no effective . I googled this problem ,and found your mail " Fri Sep 3
18:16:55 PDT 2010 " relative this issue . I want to know what's the problem in the moment, is the
speex-ec filter invalid or not?
You said that the parameters maybe wrong, what's the correct parameter ? can you get some sample?
my situation is 1-2 seconds while the echo happens, I set the ec_tail_len = 1500, ec_delay=1500,ec_framesize = 160 (my audio params is 8K ,16bits stereo).
Any advices is appreciated, thank you in advance.
Best Wishes!
"Go forward, Just chase your dream!"

Hello devs,
I am working to port Speex on to C55x platform with a bitrate of 4kbps
I am currently working with the same sample code which is been given my
settings are below
tmp=1;
speex_decoder_ctl(dec, SPEEX_SET_ENH, &tmp);
tmp=4000;/*4Kbps*/
speex_encoder_ctl(st, SPEEX_SET_BITRATE, &tmp);
tmp=1;
speex_encoder_ctl(st, SPEEX_SET_VBR, &tmp);
tmp=2.0;
speex_encoder_ctl(st,SPEEX_SET_VBR_QUALITY,&tmp);
tmp=4000;
speex_encoder_ctl(st, SPEEX_SET_VBR_MAX_BITRATE, &tmp);
tmp=1; /* Lowest */
speex_encoder_ctl(st, SPEEX_SET_COMPLEXITY, &tmp);
when i try to decode the encoded stream i face the following error
notification: More than two wideband layers found. The stream is corrupted.
notification: More than two wideband layers found. The stream is corrupted.
notification: More than two wideband layers found. The stream is corrupted.
