similar to: help regarding <voice to text>

Hi Keith, Thanks a lot for your reply. Actually I am trying to build an application in linux & C for converting a voice file(that is WAV) to a text message. This is required for one of our voice project. So just wanted to know if there is any existing application already there in linux to do that. Otherwise I have to write my own. Now to right my own "wav to text" converter I

Pintu -- Speex is an audio codec that can encode and decode audio for transmission over network (or for storage). Specifically, it's called speex because it is tailored to work well at encoding speech at small bitrates. Speex does not do speech recognition or text to speech. You may wish to look at CMU's speech page: http://www.speech.cs.cmu.edu/(look at Sphynx). And I'll tell you -

I pulled the test directory from 2003, but everything else from 2005. The 2005 files have more ?cross-compiling? targets than the 2003 ones. I fixed the various missing files in the new 2008 projects (misc.c and one other other are gone now). The only thing you could do which would make them more compact would be to get rid of the subdirectories under each vs-version. There is no real need for

Hello list users, I have been struggling with this combination in the subject field couple of days now, so I decided to ask for some advice here. Hopefully someone can point me to a right direction. The ultimate goal for me is to authenticate users using AD, so that the UID/GID values configured for users with SFU would also be in use in all our Linux machines. My understanding is that using

I need to convert .dcr files (from a Liberty Recorder) into a smaller size format that is more universally able to be listened to. After looking around quite a bit I can't seem to find anything except windows programs. I need to run it on my linux server. Any help or resources would be appreciated! -Michael -------------- next part -------------- An HTML attachment was scrubbed...

Hi, *"That's in general not very reliable. You can get PEAQ to say all sorts of silly things." Can you provide me links for any more effective tools other than PEAQ? Which is more reliable for Speex resampler? * *"strongly suspect that it's just not compensating for the delay introduced by the resampler. Because higher quality means higher delay, you'd find that PEAQ

IIRC, under ARM, I believe I was having issues with --without-libogg. I resorted to just downloading libogg sources, setting up my cross-compilation environment, and cross compiling it per the general build directions (./configure, make, make install), then went back to building speex -- everything worked like a charm for me then. So -- Conrad. *Make sure* that you have libogg cross-compiled and

Hello, I'll start a voip project, but i don't know which DSP is more indicate for the project. Any one can help me??? Which processor is more indicate for speex use ??? Thank you!! Rafael V. Gon?alves

I think TrollTech deserves a prize for their accomplishment in making qmake even worse than autotools (I'm using it for something else and wish I wasn't -- Qt itself is fine though).

List, I'm not used to work with ALSA, so it was a surprise to me when testing an ALSA-only system that it did not have /dev/dsp. In this machine, speexdec throws me an error that it won't work without /dev/dsp, so I found out that in ALSA there's stuff under /dev/snd, but everything I tried to make a link to /dev/dsp (say, /dev/snd/pcmC0D0c) reports as being the wrong IOCTL. Any

Does anybody have experience of implementing Speex encoding on low-power, low-cost bare-metal embedded hardware? I'm trying to get a feel for minimum possible hardware upon which it is possible to get a reasonable working implementation of Speex encoding. I can find little in this area on the website or via Google. Thanks, Henry

Hi all, I?m trying to send 2 frames per RTP packet. One frame is current frame , the other one is previous frame for redundancy. Can you give some recomendation?for beginning ?

I am a brand new user of Speex, so forgive my naivety. I am receiving an audio stream (PCM) which I need to encode in Speex, send it across a wire via RTP, and then decode and play the audio on the other side. I assume people have done this before, and I was wondering if anyone had any sample code of how they accomplished this. Or maybe just some good pointers or advice. Thanks Shane

I am having trouble converting a .flv file uploaded from Adobe Flex / Flash Player 10 to a Red5 server using the speex coder: http://livedocs.adobe.com/flex/3/langref/flash/media/Microphone.html http://jira.red5.org/confluence/display/codecs/Speex+Codec Questions: 1. How do I extract the audio track out of such a .flv file? 2. How do I convert it from Speex to .wav PCM? Thanks.
