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!

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.
