Voiceflint — voice agents with an itemized bill
A voice-agent platform for phone and web calls that lets builders compare speech models, inspect latency, and pay a flat platform fee.
Field notes
The platform exposes the components behind a voice call instead of presenting one undifferentiated per-minute price: speech recognition, language model, speech synthesis, managed keys, and platform usage each appear as separate lines. Its example receipt totals $0.031 per web-call minute and compares the same stack with Vapi and Retell. The page also states that phone calls add 150–300 milliseconds for carrier and SIP hops, while WebRTC voice-to-voice performance is presented at roughly 800 milliseconds.
