Ship a real-time voice agent your users want to call
Production voice pipelines built with Whisper and ElevenLabs. Fast replies, live with customers from day one. Not a demo you shelve.

The problem
Sound familiar?
Your voice demo sounds great but lags in real calls
A 600ms delay feels fine in a demo. At 1.2 seconds it feels broken. Without a latency budget, every call is full of awkward pauses.
Human call center coverage is expensive and does not scale
A 10-agent call center costs $400K to $600K a year. When volume spikes you hire or let calls queue. Neither works for a startup.
Off-the-shelf TTS sounds robotic and users hang up
Generic TTS voices trained on audiobooks do not sound like conversation. Users hear the robot at once and trust drops.
Transcription errors turn into wrong answers
If Whisper mishears a product name or number, the LLM answers with confidence on bad input. Without a correction loop, every miss costs trust.
What do we actually do?
A full real-time voice pipeline: Whisper for speech to text, ElevenLabs or Deepgram for voice, a fast orchestration layer, and a handoff to a human. Live and monitored from launch.
What changed in 2026?
In 2026 users expect a voice agent to answer in under a second and to stop when they interrupt. Anything slower sounds broken. Speech-to-text and voice models got good enough. The work is in the orchestration layer, the latency budget, and the handoff when the agent is unsure.
What's included?
- Whisper speech-to-text with noise filtering and punctuation
- ElevenLabs or Deepgram voice matched to your brand
- Orchestration layer targeting sub-800ms end-to-end response
- Handoff to a human or ticket when confidence drops
- Call transcript logging and error-rate dashboard
- Load-tested deployment on your infrastructure
- Handoff docs and 30-day post-launch bug cover
How it works
01.
Design
We map call flows, set a latency budget, and pick the STT and TTS stack.
02.
Pipeline
We wire STT, LLM, and TTS into one fast loop with streaming and interruption handling.
03.
Tune
We load test, measure P95 latency, and tune the voice until it sounds right.
04.
Deploy
We ship, wire up monitoring, and document handoff paths so your team runs it without us.
