I am interested in working with someone highly experienced in audio signal processing. I have short audio files (approx 5-10 seconds in length) with several digits spoken by a single voice over some background noise. I am looking for a skilled developer to provide me with a solution that can analyze these samples and return a string of the digits spoken. I do not care what language the solution is provided in as long as I can call it from a .dll, however, C# is preferred. Speed, accuracy, and efficiency are critical. I will provide more details in private to those qualified. Please tell me about your experience in this field and do not bid if you do not intend to finish this project in a timely manner. I refuse to work with developers that will not prioritize my project.

I had a lesson last year in university and we did the exact thing you are asking for in MATLAB. If that's not what you want, I can do it for you in java or C++. Check PM.
