Engineering & Software Development

Voice AI Integration Engineer

Turning spoken audio into usable structured data means more than calling a transcription API, it means handling speaker diarization, background noise, and delivering the output in a format your downstream systems can actually consume. We build end-to-end speech-to-text pipelines using Whisper and other ASR models, including speaker diarization and structured transcript delivery, so a voice recording becomes clean, attributed, usable text. This is for products adding meeting transcription, call analysis, or voice-driven features where raw ASR output alone isn't good enough. You get a pipeline tuned to your actual audio conditions, not one calibrated on a clean demo recording.

This is a capability we deliver for you as a service, not a role we’re hiring for.

How We’d Approach This

A clear, staged plan, not a black box

These are the service-specific steps inside our six-step process.

1
Sample real audio from your use case (call recordings, meetings, voice notes) to assess noise and speaker conditions.
2
Build a pilot pipeline with diarization against those samples and measure transcript accuracy directly.
3
Review transcript quality and speaker attribution with your team before finalizing the pipeline configuration.
4
Deploy the pipeline with structured output delivery into your downstream systems and monitor accuracy over time.
