Usage

Complete the VoiceHub installation once, then run this repository-authored example. Model pages intentionally contain no package-install command.

This example is maintained against VoiceHub's public API; it is not copied from an upstream demo or package README.

Model-specific path: Exercises Irodori-TTS's explicit no-reference path and flow sampler controls.

Inputs and controls: Set a speaker reference instead of no_reference=True when cloning an authorized voice.

from pathlib import Path

from voicehub import AutoModelForTextToSpeech, TTSGenerationConfig

model = AutoModelForTextToSpeech.from_pretrained(
    'Aratako/Irodori-TTS-500M-v3',
    model_type='irodoritts',
    device="cuda",
    lazy_load=True,
)
output = model.generate(
    'VoiceHub keeps model integrations explicit and reproducible.',
    generation_config=TTSGenerationConfig(
        seed=42,
        output_file=Path("output.wav"),
    ),
    no_reference=True,
    seconds=4.0,
    num_steps=16,
    cfg_scale_text=3.0,
)
print(output.file_path, output.sample_rate, output.metadata)

Use authorized recordings. Verify hardware needs and pin a revision in production.

Overview

irodoritts is a VoiceHub text to speech integration. This page is generated from its registry contract. Open the irodoritts Colab notebook.

Configuration

Load configuration without constructing the model:

from voicehub import AutoConfig

config = AutoConfig.for_model('irodoritts')
print(config.model_type)
Property Value
Canonical model type irodoritts
Configuration class IrodoriTTSConfig
Architecture class IrodoriTTSForTextToSpeech

Processing

Create the registered processor without allocating model weights:

from voicehub import AutoProcessor

processor = AutoProcessor.from_pretrained(
    'Aratako/Irodori-TTS-500M-v3',
    model_type='irodoritts',
)
print(type(processor).__name__)

Inference

The Usage example returns TTSOutput through AutoModelForTextToSpeech.

Input and output contract

Property Value
Readiness integrated-raw
Data architecture diffusion
Sample rate 48,000 Hz
Contract getter get_tts_dataset_spec('irodoritts')
Variant Required fields One of Boundary Other rules
raw-waveform text waveform / audio Source at most one: waveform / audio; forbidden: target_latent, latent
preencoded-latent text target_latent / latent Prepared at most one: target_latent / latent; forbidden: waveform, audio

Conditional flow-matching, rectified-flow, or diffusion data. See the data workflow.

Training and optimization

Use available_optimization_passes() to discover reversible public passes. Unsupported runtime or hardware fails closed before mutation.

Training contract

Property Value
Support native
Family flow-matching
Recipe single-phase
Default phase flow
Training checkpoint Aratako/Irodori-TTS-500M-v3
Native training graph yes
Phase Kind Components Required inputs Loss keys
flow objective model.model — loss, flow_loss, duration_loss

The integration accepts its declared source or prepared contract directly. Call model.validate_training_support() first, then follow the training workflow.

Checkpoints, provenance, license, and limitations

Property Value
Default checkpoint Aratako/Irodori-TTS-500M-v3
Hugging Face ID Aratako/Irodori-TTS-500M-v3
Repository availability verified through the Hugging Face model API on 2026-08-11; pin a revision before production use.
Checkpoint status Registry default; pin an immutable revision for production and reproducible evidence
Optional dependency extra Core package
Hardware and runtime Usage selects cuda; verify checkpoint-specific requirements
Real-checkpoint evidence Release evidence; a registry default alone is not execution evidence
Implementation voicehub.models.irodoritts.modeling_irodoritts.IrodoriTTSForTextToSpeech
Configuration voicehub.models.irodoritts.configuration_irodoritts.IrodoriTTSConfig
Source provenance voicehub/models/irodoritts/source/SOURCE.json
License Checkpoint-specific

No VoiceHub-specific license override is registered. Verify the checkpoint and upstream source terms before use.

Confirm the checkpoint revision, access terms, provenance, and license.

Limitations

  • No integration-specific checkpoint limitation is registered. Verify the selected checkpoint revision and its documented runtime requirements.
  • Validate memory, precision, and optional dependencies on the target system.
  • Public optimizations fail closed when the runtime or hardware cannot satisfy their validation contract; an unavailable pass is not reported as applied.
  • Contract tests do not replace the linked released-checkpoint evidence.
