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.
