[bot] Instrument Hume AI (52,017 weekly downloads)

[braintrust-bot]

Summary

Hume AI publishes an official Node.js/TypeScript SDK, hume on npm, providing execution APIs for text-to-speech generation and real-time Empathic Voice Interface (EVI) conversational agent execution. This repository has zero instrumentation for any Hume SDK surface — no wrapper, no diagnostics channel, no plugin, no auto-instrumentation config, no e2e scenario.

What's missing

Execution surfaces exposed by the hume npm package that are not instrumented:

SDK Method	Description
hume.tts.synthesizeJson({ utterances })	Text-to-speech generation, returns synthesized audio
hume.tts.synthesizeJsonStreaming({ utterances })	Streaming text-to-speech generation
hume.empathicVoice WebSocket connection (connect(), message handlers for assistant_message/user_message)	Real-time empathic voice conversational agent execution loop, including emotion inference on the incoming audio

None of these are covered by existing provider instrumentation — the SDK has its own REST/WebSocket client and does not depend on openai, the Vercel ai package, or any already-instrumented package.

No coverage in any instrumentation layer:

• No wrapper function (e.g. wrapHume()) in js/src/wrappers/ (52 files checked)
• No channel definitions or plugin in js/src/instrumentation/plugins/ (108 files checked)
• No auto-instrumentation config in js/src/auto-instrumentations/configs/ (34 files checked, including all.ts)
• No e2e test scenario under e2e/scenarios/
• Repo-wide case-insensitive grep for humeai/hume.ai/HumeClient returns zero matches anywhere in the repo

Braintrust docs status

not_found. Hume does not appear anywhere on the Braintrust integrations index — https://www.braintrust.dev/docs/integrations — which lists AI-provider and framework integrations (Anthropic, OpenAI, Gemini, Cohere, Groq, xAI, Voyage AI, etc.) but has no entry for Hume, empathic voice, or any TTS/voice provider. The page's only guidance for unlisted providers is the generic AI Proxy gateway or contacting Braintrust to request an integration.
