A note on what I do when I am not writing about KALDI graphs: I take on voice AI work through Voicebre Systems, a small consultancy based in Prague.
Three things, mostly: custom speech recognition — including voice commands and languages that the off-the-shelf stacks handle badly; natural language understanding for conversational systems; and end-to-end voice agents, from VUI design through to integration with whatever is already running in the business.
The interesting problems are usually not the model. They are the data you are allowed to use, the latency budget, and what happens on the turn where the user says something nobody anticipated. If that is the shape of your problem, get in touch.
