|I'd like a home-based voice recognition without some off-site cloud.|
I'd like a kind of echo dot like thing running on a set of raspberry pi devices each with a microphone and speaker. Ideally they'd be all over the house. I'm happy if they talk back via wifi to a server in my office for whatever real processing. The server might have 16 cores and 128Gb ram. Might even have two of these if required.
What options do I have? What limits? I'd really prefer answers from people who have experiences with the various options.
If it helps I'm happy to reduce vocabulary to a dictionary of words as long as I can add more words as necessary. Training is also ok. I've already analysed my voice conversations with an echo dot and the vocabulary isn't that large.
Please remember: home use, no off-site clouds. I'm not interested in options involving even a free voice speech-to-text cloud. This eliminates google voice recognition, amazon etc. They are great but out of scope.
So far I've identified CMU Sphinx as a candidate but I'm sure there are others.
