Voice Engine Architecture & Engineer Notes
How we benchmark speech recognition latency to make sure the trivia referee responds in real time.
Engineer Recommendation for Production:
In a fast-talk trivia game, audio latency is the whole game. If a player shouts "Carrot, Lettuce, Onion" and has to wait 2 seconds for a server to process, the excitement dies.
• Top Production Choice: Deepgram Nova-2. It streams live audio packets over WebSocket with sub-250ms latency and supports custom keyword boosting (so it never mishears obscure vegetables or country names).
• Browser Prototype: Web Speech API. Runs right now in your browser with zero server cost for instant testing.
| Voice Engine | Real-World Latency | Accent Handling | Stream Mechanism | Pricing / Min | Best For | Simulate |
|---|---|---|---|---|---|---|
| Deepgram Nova-2 Top Pick | < 250 ms | 95.5% (Great with fast speech) | WebSocket Audio Stream | $0.0043 / min | Competitive real-time speed games | |
| OpenAI Whisper (Groq Turbo) | 600ms - 1.1s | 97.8% (Best accent tolerance) | Batch Chunk Upload | $0.006 / min | Heavy accents and background noise | |
| Web Speech API (Active Now) | 150 - 300 ms | 92.0% (Device dependent) | Native Browser Events | $0.00 (Free) | Zero server cost, instant prototypes | |
| Google Cloud Speech v2 (Chirp) | 350 - 500 ms | 94.8% (125+ languages) | gRPC Bi-directional | $0.016 / min | Global multi-language expansion |
