Doubao Open TTS

Text-to-Speech (TTS) service using Doubao (Volcano Engine) API V1 interface to convert text into natural-sounding speech.

Features

🎙️ 200+ Voice Options - Default: Shiny (灿灿) for general scenarios
🔊 Multiple Audio Formats - Supports mp3, pcm, wav
⚡ Adjustable Parameters - Speed and volume control
📦 Dual Interface - Command-line tool + Python API
🎯 Voice Categorization - Browse voices by category
🔐 Mandatory API Configuration - Requires API credentials; stops and prompts user if not configured (default voice only available with explicit user confirmation)

Quick Start for Agents

重要提示: 当检测到没有API配置时，Agent必须立即停止并询问用户是否配置API，不允许直接使用默认音色生成音频，除非用户明确坚持使用默认音色。

When using this SKILL, the Agent should follow this workflow:

Step 1: Check API Configuration

First, check if API credentials are configured:

from scripts.tts import check_api_config, setup_api_config

# Check if API is configured
config = check_api_config()
if not config:
    # API not configured, MUST stop and ask user
    # DO NOT proceed with default voice
    print("⚠️ API credentials not found. Cannot proceed without API configuration.")
    # ... ask user for credentials or if they want to use default

Step 2: Handle Missing API Configuration

如果API凭证缺失，Agent必须停止并询问用户: 用户可以选择配置API，或者明确坚持使用默认音色（仅当用户明确要求时才允许）。

Agent: I need API credentials to use the Doubao TTS service. 
       Please provide the following information:

1. App ID (APPID)
2. Access Token
3. Secret Key

You can get these from: https://console.volcengine.com/

Please enter your App ID:

User: 4269953601

Agent: Please enter your Access Token:

User: uAGE3iP8nJf3ewu-d6U1P6Jthv7i1DH7

Agent: Please enter your Secret Key:

User: Dfta36aYgcdqY-ylHoh9FQyqiERS5iTv

Agent: [Saves credentials to .env file]
       ✅ API configuration saved successfully!

用户选择: 如果用户不想配置API但坚持使用默认音色:

User: 我不想配置API，就用默认音色吧

Agent: ⚠️ 确认使用默认音色吗？这将使用内置的默认音色生成音频。
       输入 'yes' 确认使用默认音色，或提供API凭证以获得更好的体验。

User: yes

Agent: [继续执行，使用默认音色]

Step 3: Use the Service

After API is configured OR user explicitly confirmed to use default voice:

from scripts.tts import VolcanoTTS

tts = VolcanoTTS()
output = tts.synthesize("Hello world", output_file="output.mp3")

API Configuration Detection

Function: `check_api_config()`

Checks if API credentials are available. Returns config dict or None.

from scripts.tts import check_api_config

config = check_api_config()
if config:
    print(f"App ID: {config['app_id']}")
    print(f"Access Token: {config['access_token'][:10]}...")
    print(f"Secret Key: {config['secret_key'][:10]}...")
else:
    print("API not configured")

Function: `setup_api_config(app_id, access_token, secret_key, voice_type=None)`

Saves API credentials to the .env file in the SKILL directory.

from scripts.tts import setup_api_config

# Save credentials
setup_api_config(
    app_id="4269953601",
    access_token="uAGE3iP8nJf3ewu-d6U1P6Jthv7i1DH7",
    secret_key="Dfta36aYgcdqY-ylHoh9FQyqiERS5iTv",
    voice_type="zh_female_cancan_mars_bigtts"  # optional
)

print("✅ Configuration saved to .env file")

Interactive Voice Selection

The SKILL supports interactive voice selection workflow for Agent-User collaboration:

Workflow

Agent Prompts User - Agent asks user to select a voice
Display Voice Options - Show recommended voices by category
User Selection - User tells Agent their preferred voice
Agent Calls Skill - Agent uses the selected voice to generate audio

Python API for Interactive Selection

重要: 在使用以下代码之前，必须先检查API配置。如果没有配置，必须停止并询问用户。

from scripts.tts import (
    get_voice_selection_prompt,
    find_voice_by_name,
    get_voice_info,
    check_api_config,
    VolcanoTTS
)

# Step 0: Check API configuration FIRST
config = check_api_config()
if not config:
    print("⚠️ API credentials not found. Please configure API first.")
    print("Visit: https://console.volcengine.com/")
    # STOP here and ask user to configure API
    # DO NOT proceed with voice selection until API is configured
    # OR user explicitly confirms to use default voice
    
# Step 1: Get the selection prompt to show user
prompt = get_voice_selection_prompt()
print(prompt)
# Agent displays this to user and waits for response

# Step 2: User responds with their choice (e.g., "Shiny" or "灿灿")
user_input = "Shiny"  # This comes from user

# Step 3: Find the voice_type from user input
voice_type, voice_name = find_voice_by_name(user_input)
if voice_type:
    print(f"Selected voice: {voice_name} ({voice_type})")
    
    # Get detailed info
    info = get_voice_info(voice_type)
    print(f"Category: {info['category_display']}")
    
    # Step 4: Use the voice to synthesize (API already verified)
    tts = VolcanoTTS(
        app_id="your_app_id",
        access_token="your_access_token",
        secret_key="your_secret_key"
    )
    
    output_path = tts.synthesize(
        text="Hello, this is the selected voice",
        voice_type=voice_type,
        output_file="output.mp3"
    )
    print(f"Audio saved to: {output_path}")
else:
    print("Voice not found. Please select a valid voice.")
    # DO NOT automatically use default - ask user instead

Get API Credentials

Visit Volcano Engine Console
Enable "Doubao Voice" service
Create an application in the console to get AppID, Access Token, and Secret Key
Ensure your account has sufficient TTS quota

Troubleshooting

Error: "requested resource not granted"

Cause: Account lacks TTS service permission

Solution:

Login to Volcano Engine Console
Go to "Doubao Voice" product page
Confirm service is enabled and has available quota
Check if Token has TTS calling permission

Error: "invalid auth token"

Cause: Authentication information error

Solution:

Check if AppID, Access Token, Secret Key are correct
Ensure no extra spaces

Error: "requested resource not found"

Cause: Voice type or cluster name error

Solution:

Try different voice_type, such as BV001_streaming, BV002_streaming
Try different cluster, such as volcano_tts, volcano

Test Configuration

Run test script to try multiple configurations:

python scripts/test_tts.py
