local-v15-streaming

Use this sub-skill when the task is about MOSS-TTS-Local-Transformer-v1.5 local batch inference, realtime streaming decode, browser streaming app operation, 48 kHz stereo codec-v2 audio, device/dtype split, token or duration estimates, continuation prompts, or voice-clone prompts.

Route elsewhere

• MOSS-TTS-Realtime voice-agent model, realtime conversation, or live voice-agent serving: ../realtime-voice-agent/SKILL.md.
• Generic Hugging Face family prompts, non-v1.5 model-family usage, or router-level model choice: ../hf-family-workflows/SKILL.md.
• Fine-tuning, dataset preparation, manifests, or training local v1.5: ../finetuning-data-prep/SKILL.md.
• SoundEffect v2 generation or diffusion sound-effect workflows: ../soundeffect-v2/SKILL.md.

Minimum operating facts

• Checkpoint: OpenMOSS-Team/MOSS-TTS-Local-Transformer-v1.5.
• Codec/tokenizer: OpenMOSS-Team/MOSS-Audio-Tokenizer-v2.
• Audio format: 48 kHz stereo; decoded tensors are normally [2, samples].
• Frame topology: 12.5 frames/sec, 12 RVQ layers, time-synchronous local-transformer frames.
• Backbone: Qwen3-4B-derived local transformer release.
• Default audio sampling for the app: temperature 1.7, top-p 0.8, top-k 25, repetition penalty 1.0.

Use the bundled references

• Batch inference, web streaming launch, mode semantics, and prompt patterns: references/batch-and-streaming.md.
• Python/CLI/app API fields and event contracts: references/api-reference.md.
• Failure modes and fixes: references/troubleshooting.md.
• Safe no-model estimate helper: scripts/estimate_local_v15_tokens.py.

Before claiming a v1.5 workflow is correct, verify that the runtime reports the expected sample rate (48000), RVQ depth (12), and stereo channel count, and that final output includes a WAV, audio-token dump, and metadata JSON in the configured output location.
