Abstract
Voice design from natural language aims to generate speaker timbres directly from free-form textual descriptions, allowing users to create voices tailored to specific roles, personalities, and emotions. Such controllable voice creation benefits a wide range of downstream applications-including storytelling, game dubbing, role-play agents, and conversational assistants, making it a significant task for modern Text-to-Speech models. However, existing models are largely trained on carefully recorded studio data, which produces speech that is clean and well-articulated, yet lacks the lived-in qualities of real human voices. To address these limitations, we present MOSS-VoiceGenerator, an open-source instruction-driven voice generation model that creates new timbres directly from natural language prompts. Motivated by the hypothesis that exposure to real-world acoustic variation produces more perceptually natural voices, we train on large-scale expressive speech data sourced from cinematic content. Subjective preference studies demonstrate its superiority in overall performance, instruction-following, and naturalness compared to other voice design models.

WHY NOW
Speech Synthesis moved forward this cycle; last verified April 2026. Public score 7.0/10. Production flags indicate code availability.
We present MOSS-VoiceGenerator, a fully open-source instruction-driven TTS model that generates realistic and expressive speech directly from natural language descriptions, without requiring any reference audio.
Explicitly stated as a main contribution in the abstract and analysis.
partial
Motivated by the hypothesis that exposure to real-world acoustic variation produces more perceptually natural voices, we train on large-scale expressive speech data sourced from cinematic content.
Directly stated as a motivation and supported by subjective evaluation results.
partial
MOSS-VoiceGenerator demonstrates competitive performance within the open-source landscape.
Explicitly stated conclusion based on evaluation results compared to other models.
partial
Phase 1 annotates cinematic audio via speaker diarization, denoising and quality filtering, single-speaker filtering, and ASR transcription, followed by speech captioning and timbre instruction generation. Phase 2 augments the corpus by training a speech-text embedding model for retrieval from internal TTS data.
Explicitly described in the data collection section with clear methodology.
partial
MOSS-VoiceGenerator starts from the Qwen3 checkpoint weights, and is trained end-to-end on our curated instruction-text-speech dataset. The training objective is standard next-token prediction loss over the codec token sequence. All model parameters are updated during training; we do not apply parameter-efficient methods such as LoRA.
Explicitly stated training methodology with specific technical details.
partial
Cinematic data often contains substantial background noise, and without denoising, only around 5% of the samples meet the DNSMOS 3.0 threshold. After applying MossFormer2_SE_48K for denoising, the percentage meeting the threshold increases substantially.
Directly stated with specific threshold and implied significant improvement from 5% baseline.
partial
On the commercial side, several APIs—including Elevenlabs, MiniMax, GPT-4o-TTS, and Gemini—have begun offering voice design or editing functionalities, reflecting growing market demand for instruction-driven timbre generation and customizable voice.
Directly stated market observation with specific examples of commercial APIs.
partial
MOSS-VoiceGenerator has several limitations. First, the language coverage is limited.
Explicitly stated limitation in the analysis section.
