Fluent PHP API for Chatterbox TTS

The package exposes a Laravel-inspired builder (FluentVox::make()) for configuring text, model selection (standard, turbo, multilingual), pacing, expression, and output settings before generating speech.

Voice Cloning and Multilingual Models

Developers can clone a speaker from a reference audio file or switch to the multilingual model to generate speech in 23+ languages with native pronunciation and intonation.

Hardware-Aware Acceleration

FluentVox auto-detects CUDA, Apple Metal (MPS), or CPU-only environments, selecting the fastest available device.

CLI for Installation and Generation

The bundled vendor/bin/fluentvox commands handle Python dependency setup, model downloads, environment diagnostics, and one-off audio generation or conversion.

Configurable Output and Conversion

You can set default sample rates, destinations, formats (WAV, MP3, M4A, OGG, Opus, FLAC), and convert generated audio with FFmpeg-powered helpers.

You can install this package via Composer:

composer require b7s/fluentvox
vendor/bin/fluentvox install

FluentVox requires PHP 8.3+, Python 3.10+, and benefits from CUDA or Apple Metal (MPS) when available. Use vendor/bin/fluentvox doctor to confirm system compatibility, installed models, and available devices.
