Use it every day

Honestly didn't expect to like it this much. Customizable speech models for specific domains is exactly what I needed, and developer-friendly SDKs across platforms. but I reach for it almost every day now and it just clicks.

Does the job

Pretty happy overall. Live audio moderation for voice platforms just works and supports intent and entity parsing, not just words. but no dealbreakers — I'd recommend it to a friend without hesitating.

Compared a few options

Evaluated this against two competitors. Where it wins: free developer tier for experimentation and supports intent and entity parsing, not just words. Where it lags: acquired by Roblox, raising questions about long-term public availability. On balance the feature set — especially free developer tier for experimentation — justifies the 4 stars for our use case.
