What is the current trend in using the audio file format ... aiff, mp3, wav ... ? What are the commercial speech recognition systems like Nuance or Google API .... use? Are there any archives, where one can download recorded speech files? Finally, any codes (C++ or whatever)/libraries for reading audio files so these can be processed? Thanks
