EchoForge Moss Voice

Use this skill to run voice interaction with user-preferred timbre.

Required runtime config

• MOSI_API_KEY (required)
• MOSI_BASE_URL (optional, default https://studio.mosi.cn)

Always send:

• Authorization: Bearer <MOSI_API_KEY>

Inputs

Collect:

• text (required, what to speak)
• Voice source (one of):
  • voice_id (preferred when available), or
  • reference_audio (public URL), or
  • local audio path (upload first, then clone voice)

Optional:

• expected_duration_sec
• sampling_params:
  • max_new_tokens (default 512)
  • temperature (default 1.7)
  • top_p (default 0.8)
  • top_k (default 25)
• meta_info (default false)

Workflow

1. Resolve voice source.
   • If voice_id is available, use it directly.
   • If only local audio path is available:
     • Upload file: POST /api/v1/files/upload with multipart field file.
     • Clone voice: POST /api/v1/voice/clone with file_id (or url).
     • If returned voice status is not active, poll GET /api/v1/voices/{voice_id} until ACTIVE or timeout.
   • If reference_audio URL is available, use it directly in TTS.
2. Run TTS: POST /v1/audio/tts.
   • Required payload:
     • model: "moss-tts"
     • text
     • one of voice_id or reference_audio
3. Parse response:
   • Decode audio_data (base64) to WAV.
   • Read duration_s and usage when present.
4. Return a concise result:
   • voice_id used
   • output file path
   • duration
   • brief status message

Error handling

• If 4010 or 4011: API key missing/invalid, ask user to fix MOSI_API_KEY.
• If 4020: insufficient credits, ask user to recharge.
• If 4029: rate limited, retry with exponential backoff.
• If 5002: invalid audio URL or decode failed, ask user for another clip.
• If 5004: timeout, shorten text and retry.

Operational constraints

• Keep request rate <= 5 RPM.
• Keep single request text short enough to avoid timeout.
• Never print or log raw API keys.
• Prefer reusing stable voice_id for multi-turn voice chat to reduce latency.
