api record

Uttera turns audio into text and text into audio. Use it to transcribe recordings, read text aloud, translate a recording into another language, summarise long recordings, and generate sound effects or music.

The user's API key travels in the Authorization header of this connection. If a call returns 401, tell the user their key is missing or wrong and point them at https://app.uttera.ai — do NOT try to create an account for them.

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • transcribe_audio unknown never probed

    Transcribe a recording. `audio` is an https URL or base64 audio. Use this for short recordings when you want the literal text. For anything past a few minutes prefer summarize_recording: it returns the transcript too, plus who spoke and the tone, in ONE upload instead of two.

    mcp-tool

    {
  "type": "object",
  "title": "transcribe_audioArguments",
  "required": [
    "audio"
  ],
  "properties": {
    "audio": {
      "type": "string",
      "title": "Audio"
    },
    "language": {
      "type": "string",
      "title": "Language",
      "default": ""
    }
  }
}
    arguments 18 lines
  • summarize_recording unknown never probed

    Summarise a long recording: summary, full transcript, tone, speaker profile and who spoke when — all in one request and one upload.

    mcp-tool

    {
  "type": "object",
  "title": "summarize_recordingArguments",
  "required": [
    "audio"
  ],
  "properties": {
    "audio": {
      "type": "string",
      "title": "Audio"
    },
    "language": {
      "type": "string",
      "title": "Language",
      "default": ""
    }
  }
}
    arguments 18 lines
  • identify_speakers unknown never probed

    Who speaks and when. Returns the segments with their speaker and times.

    mcp-tool

    {
  "type": "object",
  "title": "identify_speakersArguments",
  "required": [
    "audio"
  ],
  "properties": {
    "audio": {
      "type": "string",
      "title": "Audio"
    }
  }
}
    arguments 13 lines
  • speak_text unknown never probed

    Read text aloud. Returns audio. `voice` defaults to a Spanish one; call list_voices to see the catalogue. ⚠ Line breaks are billed: each one inserts a pause of about 1.3 s. Strip them from formatted text before sending it.

    mcp-tool

    {
  "type": "object",
  "title": "speak_textArguments",
  "required": [
    "text"
  ],
  "properties": {
    "text": {
      "type": "string",
      "title": "Text"
    },
    "voice": {
      "type": "string",
      "title": "Voice",
      "default": "dora"
    },
    "language": {
      "type": "string",
      "title": "Language",
      "default": ""
    }
  }
}
    arguments 23 lines
  • translate_recording unknown never probed

    Translate a recording into another language: text and, where the plan allows it, voice. `target_language` is a code such as en, es, fr, de.

    mcp-tool

    {
  "type": "object",
  "title": "translate_recordingArguments",
  "required": [
    "audio",
    "target_language"
  ],
  "properties": {
    "audio": {
      "type": "string",
      "title": "Audio"
    },
    "target_language": {
      "type": "string",
      "title": "Target Language"
    }
  }
}
    arguments 18 lines
  • generate_sound_effect unknown never probed

    One sound effect from a description: a door, rain, footsteps. Up to 30 s. Needs a paid plan (Startup and up). The description works better in English. A fixed `seed` reproduces the same sound exactly.

    mcp-tool

    {
  "type": "object",
  "title": "generate_sound_effectArguments",
  "required": [
    "description"
  ],
  "properties": {
    "seed": {
      "type": "integer",
      "title": "Seed",
      "default": -1
    },
    "seconds": {
      "type": "number",
      "title": "Seconds",
      "default": 10
    },
    "description": {
      "type": "string",
      "title": "Description"
    }
  }
}
    arguments 23 lines
  • generate_music unknown never probed

    A finished piece of music from a description. Up to 380 s. Needs a paid plan (Startup and up). ⚠ BOTH controls cost: the price is length multiplied by steps, so 380 s at 128 steps is about eight times a 60 s at 32. Naming style, instruments and BPM helps far more than asking for «something upbeat».

    mcp-tool

    {
  "type": "object",
  "title": "generate_musicArguments",
  "required": [
    "description"
  ],
  "properties": {
    "seed": {
      "type": "integer",
      "title": "Seed",
      "default": -1
    },
    "steps": {
      "type": "integer",
      "title": "Steps",
      "default": 32
    },
    "seconds": {
      "type": "number",
      "title": "Seconds",
      "default": 60
    },
    "description": {
      "type": "string",
      "title": "Description"
    }
  }
}
    arguments 28 lines
  • list_voices unknown never probed

    The voice catalogue, with the language each one speaks.

    mcp-tool

    {
  "type": "object",
  "title": "list_voicesArguments",
  "properties": {}
}
    arguments 5 lines
  • last_call_cost unknown never probed

    What the previous call actually cost, in credits, broken down. Worth checking before running something many times: it is the honest way to tell the user what a batch is going to cost them.

    mcp-tool

    {
  "type": "object",
  "title": "last_call_costArguments",
  "properties": {}
}
    arguments 5 lines
_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
