Turn text into speech, voice, and audio at scale

MarketingCommunicationProductivityDocumentsAI

Camb.ai is an AI-powered audio platform that converts text to speech, clones voices, transcribes recordings, translates content, and generates sound effects or music from a prompt. Connect it to Actionist and your agents can narrate documents, localise content into dozens of languages, transcribe meeting recordings, build branded voice personas, and produce production-ready audio — all without a studio or a recording engineer.

Eliminates manual work. Agents eliminate manual call transcription, studio recording sessions, copy-paste translation, and voice message listen-back — the repetitive audio processing that fills team members' mornings.

Blog post narrated and posted automatically

When a blog post is published in Notion, the agent extracts the article body, synthesizes it using the brand narrator voice in MARS Pro, uploads the WAV file to Google Drive, and posts the audio link to the #content Slack channel alongside the written post link — listeners get the content the moment it goes live.

With Actionist

What your agent runs for you

  • Sales
    75 min / week
    Manual call notes after every recording

  • Marketing
    120 min / week
    Studio booking for every audio piece

    Agent synthesizes brand-voice audio on demand

    The Marketing Agent synthesizes narrated audio for every published post and translates campaign copy into five languages automatically — no studio, no waiting, no scheduling.

  • Customer Support
    40 min / week
    Manual voicemail listen and ticket creation

    Support agents listen to each voice message, type out what the customer said, and manually create a ticket — adding minutes to every voice interaction at the start of the week.

    Customer Support Agent
    0 min
    Agent transcribes voice messages into ready-to-action tickets

    The Customer Support Agent transcribes all voice messages overnight and creates tickets with the full transcript attached, so agents read rather than listen their way into Monday.

  • Human Resources
    90 min / week
    Training narration recorded by hand

    HR coordinators read training scripts into a USB microphone, edit the files in Audacity, re-record whenever the script changes, and manually upload each section to the LMS.

    Human Resources Agent
    0 min
    Agent narrates training modules with consistent brand voice

    The Human Resources Agent synthesizes each module section with a measured, instructional tone and uploads the audio to the LMS — every script change triggers an automatic re-narration.

  • Finance
    60 min / week
    Manual meeting note-taking and translation

    A finance assistant sits in on every board and budget meeting to take notes by hand, then spends additional hours translating summaries for regional offices.

    Finance Agent

    Agent transcribes meetings and translates summaries automatically

  • Operations
    50 min / week
    Field recordings reviewed and typed up manually

  • Legal

    Deposition transcription outsourced to a service

    Legal transcription is sent to a third-party service, taking 24–48 hours to return and costing per-minute fees that add up across dozens of depositions per year.

FAQs

Questions about Camb.ai + Actionist

How does Actionist connect to Camb.ai?
Go to the Apps tab in Actionist, find Camb.ai, and click Connect. You will need a Camb.ai API key, which you generate at studio.camb.ai under Settings → API Keys. Paste the key into the API Key field and click Test connection — Actionist calls the list-voices endpoint to confirm the credentials are valid before any synthesis or transcription job runs.
Which Camb.ai TTS models does Actionist support?
Actionist exposes all three MARS models available through the Camb.ai API: MARS Flash (22.05 kHz, fast inference, recommended for most tasks), MARS Pro (48 kHz, higher fidelity, best for customer-facing audio), and MARS Instruct (22.05 kHz, accepts style and tone instructions for fine-grained control over delivery). You choose the model per synthesis job based on the quality and speed trade-off you need.
Can agents use a cloned or custom brand voice for synthesis?
Yes. Use the Clone Voice action to create a voice from a 30–60 second audio sample of your narrator, or use Create Voice from Description to generate a synthetic voice from a text description. Once registered, the voice is listed by List Available Voices and its ID can be used in any Synthesize Text to Speech or Translated TTS call. The agent can confirm the voice is available before running a batch synthesis job.
How long does it take for Camb.ai to process a transcription or translation?
Processing time depends on file length and the model. Short files (under 5 minutes) typically complete within about a minute. Longer recordings or translated TTS jobs use Camb.ai's async task pattern — the API returns a task ID and Actionist polls for the result until the task reaches SUCCESS status before handing off the output to downstream steps.
Can Actionist transcribe recordings with multiple speakers?
Yes. The Transcribe Audio and Transcribe and Identify Speakers actions both return timestamped segments with a speaker label per segment. The agent can attribute statements to individual speakers for tasks like meeting minutes, sales call analysis, or deposition transcripts — making downstream extraction (action items, objections, commitments) significantly more accurate.
What languages does Camb.ai support for translation and multilingual TTS?
Camb.ai supports a wide range of languages for both text translation and translated TTS. Languages are referenced by numeric language IDs in the API (1 = English). Common supported languages include Spanish, French, German, Portuguese, Japanese, Korean, Italian, and many more. Check the Camb.ai documentation at docs.camb.ai for the full list of supported language IDs before building a localisation pipeline.
Can the agent clean noisy audio before transcribing it?
Yes. Chain the Separate Audio Tracks action before Transcribe Audio. Separate Audio Tracks calls Camb.ai's audio separation API to isolate the foreground vocals from background noise, returning a clean vocal file. The agent then transcribes the clean track rather than the original noisy recording, which meaningfully improves accuracy for field recordings, large-room meetings, or recordings made on consumer hardware.
What output formats does the Synthesize Text to Speech action support?
The synthesis action supports WAV, FLAC, AAC (ADTS), and raw PCM 16-bit little-endian (PCM S16LE). The output format is specified per synthesis call. For most downstream use cases — email attachments, Google Drive uploads, podcast platforms — WAV is the safest choice. FLAC is preferable if you need lossless compression. AAC is best for streaming contexts. PCM S16LE is for custom audio processing pipelines.
