- Thread-topic: Need to hire a software developer for a voice processing app!
Casa Futura Technologies is the leading manufacturer of electronic assistive
devices for speech disorders. We need to hire a software developer to make a
prototype speech aid for Parkinson's patients. We believe it should be easy
to develop it as a Macintosh app, using Audio Units provided by Apple. If
the prototype is effective in clinical trials we will then have the
Macintosh app ported to the iPhone. (When will Apple include Audio Units in
the iPhone operating system?)
The app provides the user's voice to the user's ears in real time, altered
in several ways. The Audio Units used are:
- AUDelay. 50 to 200 milliseconds. Receives input from the microphone,
outputs the delayed signal to the headphones.
- AUPitch. -1 to +1 octaves. Receives input from the microphone, outputs the
pitch-shifted signal to the headphones.
- AUAudioFilePlayer and AUMixer. Takes an audio data file of masking noise
(I have this on a CD) and mixes it with the delayed and pitch-shifted audio
signal.
I also need to have the microphone input volume analyzed (i.e., how loud the
user is speaking) and then inversely relate the masking noise output volume.
I.e., when the user is speaking too quietly, he receives loud masking noise
in his headphones to induce the Lombard effect, which induces him to speak
louder. When he speaks louder, the volume of the (annoying) masking noise
drops, as a biofeedback positive reward. There should also be a graphic
display of vocal volume.
In a later version I would like to have a pitch analyzer too.
Parkinson's patients lose their ability to move their speech muscles
sufficiently, resulting in quiet, inarticulate mumbling. The masking noise
induces them to speak louder, the pitch shift makes them speak more clearly,
and the delay steadies their pacing. You can watch a video of Parkinson's
patients using our devices on our website.
I have a patent pending on all this, so no need for a non-disclosure
agreement.
Please recommend anyone you know who is qualified to develop this app. If
you wish to develop this app for us, please send us a time and cost
estimate.
