OHF-Voice/piper1-gpl

Features

• Neural Text-to-Speech Engines - Implements a deep learning pipeline that translates characters into phonemes and generates raw audio waveforms.
• Multi-Language Speech Generators - Supports a wide variety of global languages and regional dialects through language-specific neural pipelines.
• Voice Model Trainers - Provides a toolkit for training custom single-speaker or multi-speaker voice models from recordings and transcripts.
• Voice Synthesizer Training - Implements a toolkit for training neural text-to-speech models to mimic specific target speakers.
• Multi-Speaker Training - Supports training a single model to synthesize multiple distinct voices by linking recordings to unique speaker identifiers.
• Multi-Speaker Synthesis - Enables the development of a single neural model capable of synthesizing multiple distinct voices and regional dialects.
• Speaker Embeddings - Uses unique speaker identifiers to link multiple distinct voices within a single neural model.
• Text-to-Speech Synthesis - Provides an HTTP interface for converting written text into spoken audio with adjustable speed and variability.
• ONNX-Based Engines - Implements a neural speech synthesis system using ONNX models for high-performance offline inference.
• Phoneme-Based Speech Processors - Converts text into a sequence of specific speech sounds to ensure precise pronunciation and intonation.
• Multi-Language Speech Generators - Synthesizes spoken audio across a wide variety of global languages and regional dialects.
• GPU Acceleration - Provides hardware acceleration via graphics processors to increase the speed of neural audio generation.
• Hardware-Accelerated Inference - Offloads neural network computations to GPUs to increase the speed of audio generation.
• ONNX Model Exporters - Converts trained neural network checkpoints into the standardized ONNX format for cross-platform acceleration.
• Vocal Characteristic Adjustments - Provides tools to modify the volume, speaking speed, and audio variation of generated speech.
• Audio File Exports - Converts text into spoken audio and writes the resulting sound directly to waveform files.
• Local Speech Synthesis - Supports local speech generation by using pre-trained models exported to formats like ONNX for standalone use.
• Raw Phoneme Injection - Allows for precise pronunciation control by inserting specific phonemes into text blocks to override automatic conversion.
• Phonetic Pronunciation Overrides - Allows manual overriding of text-to-phoneme conversion using raw phoneme IDs for exact pronunciation.
• Weight-Based Initializations - Supports starting new voice model training from existing model weights to reduce compute and convergence time.
• Generative Audio Chunking - Produces synthesized audio in incremental chunks to allow playback to begin before processing is complete.
• Streaming Audio Generators - Generates spoken audio incrementally to enable immediate playback while the remaining text is being processed.
• Live Synthesis Streaming - Streams synthesized speech in incremental chunks to allow playback to begin before the full text is processed.
• GPU-Accelerated TTS - Uses graphics processors to accelerate the neural speech synthesis process.
