Speech Recognition & Audio AI

Turn raw audio into meaningful data.

Speech-to-text, transcription, speaker diarization, voice analytics and multilingual audio processing, engineered for accuracy in real-world, noisy conditions.

About this service

Most of an organisation's spoken knowledge never becomes usable data.

We build audio intelligence pipelines using Whisper and best-in-class ASR models, with layered analytics, sentiment, topics, entities, summaries, compliance flags, and deployment options from managed cloud APIs to fully self-hosted deployment for sensitive audio.

What we deliver

  1. Speech-to-text (ASR)

    High-accuracy transcription of calls, meetings and media, with punctuation, formatting and domain-specific vocabulary.

  2. Speaker diarization

    Automatically separate and label who spoke when, even in overlapping, multi-party conversations.

  3. Voice analytics

    Sentiment, intent, topics, keywords, and talk-time analysis.

  4. Multilingual processing

    Transcription and translation across dozens of languages, including code-switched speech.

  5. Real-time streaming

    Live captions and low-latency transcription for voice agents and contact centres.

  6. Redaction & compliance

    Automatic PII/PHI detection and redaction to keep sensitive audio inside your compliance boundary.

Frequently asked questions

Can we keep audio on our own infrastructure?

Yes. Whisper and several ASR models can be self-hosted on your GPUs, so audio never leaves your environment.

How accurate is it on our specific audio?

We benchmark on your real recordings and improve results with custom vocabulary, domain tuning and LLM post-correction.

Do you support real-time transcription?

Yes, for streaming use cases like live captions and voice agents, using low-latency models.
