Celune-1.7B-Neutral

Celune - Neutral

“It’s not just a TTS, it’s a character.”

Celune is a single-speaker neural TTS voice built on top of Qwen3-TTS. This model defines one identity, one voice, and one consistent speaking style.

Overview

• Model: Qwen3-TTS-12Hz-1.7B-Base (finetuned)
• Type: Single-speaker voice
• Language: English + 9 others
• Style: Default, unstyled TTS delivery

This is part of the Celune voice lineup, where each model represents a distinct interpretation of the same character.

Voice Description

The default voice mode. Designed for straightforward text-to-speech with clear, natural delivery and no added stylistic bias.

Characteristics

• Consistent timbre across generations
• Expanded expressiveness beyond reference audio
• Supports prompt-based tone steering
• Stable pacing and pronunciation
• Designed for real-time or near real-time usage

Usage

Basic Example

import numpy as np
import soundfile as sf
from faster_qwen3_tts import FasterQwen3TTS

model = FasterQwen3TTS.from_pretrained("lunahr/Celune-1.7B-Neutral")

buffer = []
for audio_chunk, sr, timing in model.generate_custom_voice_streaming(
    text="Hello, this is Celune.",
    language="Auto",
    speaker="celune"
):
    buffer.append(audio_chunk)

wav = np.concatenate(buffer)
sf.write("output.wav", wav, 24000)

Sample Output

<audio controls> <source src="https://huggingface.co/lunahr/Celune-1.7B-Neutral/resolve/main/sample.wav?download=true" type="audio/wav"> </audio>

Prompt Steering

You can influence delivery style using text or instruct prompts:

Examples:

• “whisper this softly”
• “speak with excitement”
• “calm and slow delivery”

The model will stay within the defined voice but expand expression.

Notes

• This is a single-speaker model. It does not support multiple voices.
• Voice identity is fixed and defined by training data.
• Avoid mixing languages mid-sentence for best stability.
• Avoid special tokens or markup in spoken text.

Intended Use

• Character voices
• Assistive TTS
• Offline voice systems
• Creative projects and prototyping

Limitations

• Not designed for multi-speaker tasks
• Extreme prompts may introduce instability
• Long mixed-language inputs may degrade output

About Celune

Celune is a local-first TTS system focused on speed, control, and identity.

Each model in the Celune lineup is:

• self-contained
• stylistically distinct
• built around the same core character concept
