doubao-tts

ByteDance Doubao speech synthesis model. Supports multiple languages, voices, and highly natural streaming audio output, suitable for news broadcasts and audiobooks.

Overview

Field	Value
Model ID	`doubao-tts`
CLI	`dlazy doubao-tts`
MCP	`doubao-tts` (Claude Code surfaces this as `mcp__dlazy__doubao-tts`)
Type	`audio`
Execution	Async task; the CLI polls until completion (`--no-wait` returns `generateId` immediately)
Batch	Supports `--batch <n>` parallel fan-out

Parameters

Arg	Type	Required	Notes
`prompt`	string	Yes	Prompt
`voice_language`	"zh-cn" \| "en"	No	Voice Language; default `"zh-cn"`
`voiceId`	string	No	Voice ID Options depend on "voice_language"; default `"zh_female_shuangkuaisisi_uranus_bigtts"`; options depend on `--voice_language` (see "Dynamic Options")
`speed_ratio`	"0.8" \| "1.0" \| "1.2" \| "1.5" \| "2.0"	No	Speed Ratio; default `"1.0"`

--input @file.json or --input '{...}' can supply all args at once; flags take precedence over --input keys.

CLI Examples

dlazy doubao-tts --help
dlazy doubao-tts --prompt "Write your prompt here"
dlazy doubao-tts --prompt "Write your prompt here" --dry-run
dlazy doubao-tts --prompt "Write your prompt here" --no-wait
dlazy doubao-tts --prompt "Write your prompt here" --batch 4

MCP is consumed by AI clients, not handwritten. Once dLazy is registered as an MCP server the tool appears in the client's tool list — Claude Code surfaces it as mcp__dlazy__doubao-tts; generic clients (e.g. OpenClaw) call it as doubao-tts.

See MCP setup for how to add the server.

Output

{
  "outputs": [
    { "type": "audio", "id": "o_...", "url": "https://files.dlazy.com/result.mp3", "mimeType": "audio/mpeg" }
  ]
}

Media tools emit image / video / audio / file outputs. Use --output url to print only the URLs on stdout.
