Production-Grade 4-Tier On-Device Speech Synthesis Framework for Mobile & Edge (Zero-Dependency DSP Formant, C++ Vulkan GPU Neural Engine & Android Native Voice Bridge)

Installation

pip install termux-tts

1-Click Automated Engine Provisioning

termux-tts install --tier high

Quickstart

import termux_tts as tts

# 1. Studio Vulkan GPU Neural Engine
with tts.load(engine="vulkan", model_tier="high") as engine:
    result = engine.synthesize("Neural speech synthesis on mobile GPU.", output="speech.wav")
    print(f"Elapsed: {result.elapsed_ms:.1f}ms (RTF: {result.rtf:.4f}x)")

# 2. Zero-Dependency DSP Formant Mode
with tts.load(engine="dsp", preset="balanced") as engine:
    result = engine.synthesize("Instant speech generation.", output="dsp.wav")
    print(f"DSP Latency: {result.elapsed_ms:.1f}ms")

# 3. Direct Android Native Speaker Output
with tts.load(engine="native", language="en") as engine:
    engine.speak("Direct hardware speaker output.")
