assemblyai-transcribe（汇编转录）

AssemblyAI transcription, Speech Understanding, and agent-friendly exports

Use this skill when the user wants AssemblyAI rather than generic transcription, or when the job benefits from AssemblyAI-specific capabilities such as:

• model routing across universal-3-pro and universal-2
• language detection and code switching
• diarisation plus speaker name / role mapping
• translation, custom formatting, or AssemblyAI speaker identification
• subtitles, paragraphs, sentences, topic / entity / sentiment tasks
• transcript output that is easy for other agents to consume as Markdown or normalised JSON

The skill is designed for AI agents like OpenClaw, not just end users. It provides:

1. A no-dependency Node CLI in scripts/assemblyai.mjs (and a compatibility wrapper at assemblyai.mjs)
2. Bundled model/language knowledge via models and languages commands
3. Stable transcript output formats

- agent-friendly Markdown - normalised agent JSON - bundle manifests for downstream automation

1. Speaker mapping workflows

- manual speaker/channel maps - AssemblyAI speaker identification - merged display names in both Markdown and JSON

1. AssemblyAI LLM Gateway integration for structured extraction from transcripts

Use this skill in this order

1) Decide whether the user needs AssemblyAI-specific behaviour

If they just want “a transcript”, a generic solution may be enough. Reach for this skill when the user mentions AssemblyAI, wants a specific AssemblyAI feature, or needs the richer outputs and post-processing this skill provides.

2) Pick the best entry point

• New transcription → transcribe
• Existing transcript id → get or wait
• Re-render existing saved JSON → format
• Post-process an existing transcript → understand
• Run transcript text through LLM Gateway → llm
• Need a quick capability lookup before deciding → models or languages

3) Prefer the agent-friendly defaults

For most unknown-language or mixed-language jobs, prefer:

node {baseDir}/assemblyai.mjs transcribe INPUT   --bundle-dir ./assemblyai-out   --all-exports

Why:

• the CLI defaults to auto-best routing when models are not specified
• it writes a manifest + multiple files that agents can inspect without reparsing terminal output
• Markdown and agent JSON become available immediately for follow-on steps

Quick-start recipes

Best general default

Use this when the source language is unknown or could be outside the 6-language Universal-3-Pro set:

node {baseDir}/assemblyai.mjs transcribe ./meeting.mp3   --bundle-dir ./out   --all-exports

This defaults to model routing plus language detection unless the request already specifies a model or language.

Best known-language accuracy

If the language is known and supported by Universal-3-Pro, prefer an explicit request:

node {baseDir}/assemblyai.mjs transcribe ./meeting.mp3   --speech-model universal-3-pro   --language-code en_us   --bundle-dir ./out

Meeting / interview with speaker labels

node {baseDir}/assemblyai.mjs transcribe ./meeting.mp3   --speaker-labels   --bundle-dir ./out

Add explicit speaker names or roles

Manual mapping:

node {baseDir}/assemblyai.mjs transcribe ./meeting.mp3   --speaker-labels   --speaker-map @assets/speaker-map.example.json   --bundle-dir ./out

AssemblyAI speaker identification:

node {baseDir}/assemblyai.mjs transcribe ./meeting.mp3   --speaker-labels   --speaker-type role   --known-speakers "host,guest"   --bundle-dir ./out

Or post-process an existing transcript:

node {baseDir}/assemblyai.mjs understand TRANSCRIPT_ID   --speaker-type name   --speaker-profiles @assets/speaker-profiles-name.example.json   --bundle-dir ./out

Translation

node {baseDir}/assemblyai.mjs transcribe ./meeting.mp3   --translate-to de,fr   --match-original-utterance   --bundle-dir ./out

Structured extraction through LLM Gateway

node {baseDir}/assemblyai.mjs llm TRANSCRIPT_ID   --prompt @assets/example-prompt.txt   --schema @assets/llm-json-schema.example.json   --out ./summary.json

Command guidance

transcribe

Use for local files or remote URLs.

• Local files are uploaded first.
• Public URLs are sent directly to AssemblyAI.
• Waits by default, then renders output.

Prefer --bundle-dir for anything longer than a trivial clip.

get / wait

Use when you already have the transcript id. wait blocks until completion; get fetches immediately unless you add --wait.

format

Use when you already saved:

• raw transcript JSON from AssemblyAI, or
• the normalised agent JSON produced by this skill

This is useful when you want to apply a new speaker map, re-render Markdown, or generate a fresh bundle without retranscribing.

understand

Use when you need AssemblyAI Speech Understanding on an existing transcript:

• translation
• speaker identification
• custom formatting

This command fetches the transcript, merges in the returned understanding results, then renders updated Markdown / agent JSON / bundle outputs.

llm

Use when the user wants:

• summaries
• extraction
• structured JSON
• downstream reasoning over the transcript

Prefer --schema when the next step is automated.

Output strategy

Best default for agents: bundle mode

--bundle-dir writes a directory containing:

• Markdown transcript
• agent JSON
• raw JSON
• optional paragraphs / sentences / subtitles
• a machine-readable manifest

This is usually better than dumping everything to stdout.

Primary output kinds

Use --export to choose the main output:

• markdown (default)
• agent-json
• json / raw-json
• text
• paragraphs
• sentences
• srt
• vtt
• manifest

Sidecar outputs

You can request extra files directly with:

• --markdown-out
• --agent-json-out
• --raw-json-out
• --paragraphs-out
• --sentences-out
• --srt-out
• --vtt-out
• --understanding-json-out

Speaker mapping rules

Speaker display names are merged in this order:

1. manual --speaker-map
2. AssemblyAI speaker identification mapping
3. fallback generic names like Speaker A or Channel 1

This means you can let AssemblyAI identify speakers first, then still override individual display names later.

Example manual map file: assets/speaker-map.example.json

Model and language lookup

Before choosing parameters, inspect the bundled reference data:

node {baseDir}/assemblyai.mjs models
node {baseDir}/assemblyai.mjs models --format json
node {baseDir}/assemblyai.mjs languages --model universal-3-pro
node {baseDir}/assemblyai.mjs languages --model universal-2 --codes --format json

The bundled data lives in:

• assets/model-capabilities.json
• assets/language-codes.json

Important operating notes

• Keep API keys out of chat logs; use environment injection.
• Use the EU AssemblyAI base URL when the user explicitly needs EU processing.
• Uploads and transcript creation must use API keys from the same AssemblyAI project.
• Prefer --bundle-dir or --out for long outputs.
• The CLI is non-interactive and sends diagnostics to stderr, which makes it easier for agents to script reliably.
• Use raw --config or --request when you need a newly added AssemblyAI parameter that this skill has not exposed yet.

Key bundled files

• assets/custom-spelling.example.json
• assets/llm-json-schema.example.json
• assets/transcript-agent-json-schema.json

Sanity checks before finishing a task

• Did you pick the right region (api.assemblyai.com vs api.eu.assemblyai.com)?
• Did you choose a model strategy that matches the language situation?
• If speaker naming matters, did you enable diarisation and/or provide a speaker map?
• If the result will feed another agent, did you produce Markdown and/or agent JSON rather than only raw stdout?
• If the transcript will be machine-consumed, did you keep the manifest or explicit output filenames?
