STT

Burki + Azure AI Speech

Enterprise STT/TTS for Microsoft-aligned deployments.

Azure AI Speech is the right STT/TTS choice for enterprise deployments inside Microsoft-aligned IT environments — government, large financial, and healthcare orgs that already standardize on Azure. Burki ships full Azure adapters for both speech directions.

Why connect Azure AI Speech to Burki?

A voice AI assistant is only useful when it can connect to the rest of your stack. The Azure AI Speech integration helps Burki fit into the systems your team already uses for calling, transcription, reasoning, speech, routing, or customer data. That means the assistant can move from a demo into a production workflow without forcing you to replace your existing tools.

Burki keeps the integration flexible. You can run one assistant with Azure AI Speech, pair it with other providers for a full voice pipeline, and change providers later if your cost, latency, coverage, or quality requirements change. This is especially useful for teams that need different settings per assistant, region, campaign, or customer segment.

The result is a voice agent that is easier to operate: fewer hard-coded assumptions, clearer provider boundaries, and a pricing model that separates Burki's platform fee from the third-party services you already trust.

What you get with Burki + Azure AI Speech

Streaming STT with custom vocabulary and acoustic models
Neural TTS voices including custom-trained brand voices
Regional data residency (US, EU, UK, Canada, AU, India, Japan)
Compliance: HIPAA, FedRAMP High, SOC 2, GDPR aligned out-of-box
Direct integration with Azure AD for SSO scenarios

When to choose Azure AI Speech

Choose Azure when compliance, regional residency, or Microsoft-stack alignment are hard requirements. Choose Deepgram + ElevenLabs for raw performance and cost in less-regulated environments.
