Microsoft's bot orchestration SDK with voice channels via Direct Line Speech.
Upstream is archived. Microsoft Bot Framework (Voice)’s repository has been set read-only by its owner, so there are no further releases, fixes, or security patches. The last commit landed 2025-12-29. It can still be cloned and run, and forks may be maintained elsewhere. See the repository.
Best for azure-native teams building bots that span Teams, web, and voice. Pricing: see vendor pricing.
What it is
Microsoft Bot Framework remains a mature SDK and bot service for enterprise conversational AI on Azure. The Direct Line Speech channel exposes a voice surface, and integration with Azure AI Speech provides ASR and TTS. Microsoft is steering new builds toward Copilot Studio (Power Virtual Agents) but Bot Framework is still widely deployed.
Watch out for: LLM-native experiences typically use newer Copilot/Power Virtual Agents stack instead.

How is Whipscribe different from Microsoft Bot Framework (Voice)?

The first 20 minutes of any recording are transcribed free, and a pack from $6 (500 minutes) transcribes the rest and opens every export.

There is no subscription and no monthly minimum: a 3-hour recording is about $2.16, a thousand-hour archive is about $720 once.

Where is the Microsoft Bot Framework (Voice) category heading?
Three things are moving across the whole speech-to-text market right now: summaries, action items and speaker insights generated on top of the transcript rather than sold separately; private, secured deployment where the audio never leaves a boundary you control; and agent access — transcription exposed as a tool that Claude, Cursor or a workflow runner can call directly. Whipscribe ships all three today: per-job insights, our own servers, and an MCP server.
Whipscribe is a hosted transcription service. If you want transcripts without running infrastructure, paste a URL or drop a file in the form below — you'll have a transcript in seconds.
