🌸 Suzune S1 Mini (40M On-Device Causal Flow TTS)

Suzune S1 Mini is an ultra-compact, 40-million parameter on-device Text-to-Speech (TTS) foundation model engineered by Sorika Labs.

Powered by causal flow-matching and neural latent acoustic decoding, Suzune S1 Mini delivers time-to-first-audio latency of under 10ms directly on laptop CPUs, mobile devices, edge compute, and Apple Silicon, with zero network round-trip.

🏛️ Base Model & Lineage

Lineage & Attribution: Suzune S1 Mini is developed and released by Sorika Labs. Its underlying causal flow-matching acoustic architecture is adapted and fine-tuned from the open-source gradium/phonon-31m-en foundation (released under Apache 2.0).

Sorika Labs Enhancements & Customizations:

1. Calibrated High-Fidelity Voice Manifolds: Built-in voice profiles including Zoey, Harper, Easton, Juniper, Austin, and Aria.
2. Causal Acoustic Optimization: Streamlined latent flow generation for sub-10ms real-time conversational agents.
3. Standalone suzune-mini SDK: Clean, high-level Python API with zero complex boilerplate.

🚀 Installation

pip install suzune-mini

Or install the master unified framework:

pip install suzune

🎙️ Python Quickstart

Generate speech in 3 lines of code:

import suzune_mini

# Load Suzune Mini engine (default voice: 'Zoey')
tts = suzune_mini.load(voice="Zoey")

# Synthesize speech
audio, sr = tts.speak(
    "Hello! Suzune Mini is running 100% on device with sub-10ms latency.",
    output="speech.wav"
)

Using the unified suzune SDK:

import suzune

mini = suzune.load("mini", voice="Harper")
mini.speak("Suzune Mini delivers natural speech right on your CPU.", output="speech.wav")
