gemini tts

[grave finch]

I was looking in the documentation and can't find where this block would go within the openclaw.json:

{
messages: {
tts: {
auto: "always",
provider: "google",
providers: {
google: {
model: "gemini-3.1-flash-tts-preview",
voiceName: "Kore",
},
},
},
},
}

It goes at the top level of openclaw.json, under messages.

So if you already have other top-level sections like gateway, models, or channels, it would look like:

{
  gateway: {
    // ...
  },

  models: {
    // ...
  },

  messages: {
    tts: {

      auto: "always",
      provider: "google",
      providers: {
        google: {
          model: "gemini-3.1-flash-tts-preview",
          voiceName: "Kore",
        },
      },
    },
  },

  channels: {
    // ...
  },
}

If you already have a messages block, just merge tts into that existing block. Don’t create a second messages key.

Docs:

• TTS: https://docs.openclaw.ai/tools/tts
• Google provider: https://docs.openclaw.ai/providers/google
• Config reference: https://docs.openclaw.ai/gateway/configuration

Also, openclaw.json is JSON5, so unquoted keys and trailing commas like your example are fine.

[grave finch]

everything in my openclaw.json has keys quoted, can it be either way?

[sharp silo]

Yep, either way is fine.

openclaw.json is parsed as JSON5, so these are both valid:

{
  messages: {
    tts: {
      auto: "always"
    }
  }
}

and

{
  "messages": {
    "tts": {
      "auto": "always"
    }
  }
}

If your file already uses quoted keys, I’d just keep it consistent and use quotes everywhere.

A few handy JSON5 extras:

• trailing commas are okay
• comments are okay
• unquoted keys are okay when they’re simple identifiers

So your block with quotes would be:

{
  "messages": {
    "tts": {
      "auto": "always",
      "provider": "google",
      "providers": {
        "google": {
          "model": "gemini-3.1-flash-tts-preview",
          "voiceName": "Kore"
        }
      }
    }
  }

}
