good project, going in the right direction... models are getting more efficient, meaning more and more of them can run locally on less powerful phones... we're building many examples in this area, some fully offline, some hybrid
This is a cool use case. Is any of the voice AI running on-device already? If you're planning to do some of the processing on-device and/or cross platform, we're working on some dev tools you might find useful (free to 10K MAUs / cheap after that + lots of open source coming soon). Check out switchboard.audio or feel free to hit me up; always interested in chatting about new use cases in real time voice AI, especially in the consumer space where local/hybrid audio pipelines are useful.
Definitely still a need for this product. We built an "audio slack" app with some similarities to this a decade ago and it was too early at that time for various reasons. But there's definitely a need for it and now the AI capabilities are far better than what we were working with back then. Good timing.
At some point I suspect you'll want offline functionality / on-device for some aspects of it. Would be interested to chat if you do. Look us up at switchboard.audio -- we are now building dev tools for applications like yours.
Cool use case, I have a friend who's starting to experiment in this space as well. Planning to distribute via therapists? Have you explored on-device processing at all (e.g. for latency / cost / privacy reasons?).
