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: Uses Inflect's normalized-text frontend with explicit speed and variation controls.

Inputs and controls: Set input_is_phonemes=True only when supplying checkpoint-compatible phoneme text.

from pathlib import Path

from voicehub import AutoModelForTextToSpeech, TTSGenerationConfig

model = AutoModelForTextToSpeech.from_pretrained(
    'owensong/Inflect-Micro-v2',
    model_type='inflecttts',
    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"),
    ),
    speed=1.0,
    variation=0.3,
)
print(output.file_path, output.sample_rate, output.metadata)

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

Overview

Configuration

Load configuration without constructing the model:

from voicehub import AutoConfig

config = AutoConfig.for_model('inflecttts')
print(config.model_type)
Property Value
Canonical model type inflecttts
Configuration class InflectTTSConfig
Architecture class InflectTTSForTextToSpeech

Processing

Create the registered processor without allocating model weights:

from voicehub import AutoProcessor

processor = AutoProcessor.from_pretrained(
    'owensong/Inflect-Micro-v2',
    model_type='inflecttts',
)
print(type(processor).__name__)

Inference

The Usage example returns TTSOutput through AutoModelForTextToSpeech.

Input and output contract

Property Value
Readiness preprocessed
Data architecture vits
Sample rate 24,000 Hz
Contract getter get_tts_dataset_spec('inflecttts')
Variant Required fields One of Boundary Other rules
explicit-features input_ids, spectrogram, audio_values — Prepared —

VITS/GAN text, waveform, spectrogram, and adversarial 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 preprocessed
Family vits
Recipe adversarial
Default phase generator
Training checkpoint owensong/Inflect-Micro-v2
Native training graph yes
Phase Kind Components Required inputs Loss keys
generator generator training_model.generator input_ids, input_lengths, spectrogram, spectrogram_lengths, audio_values loss, mel_loss, kl_loss, duration_loss, adversarial_loss, feature_matching_loss, waveform_loss
discriminator discriminator training_model.discriminator input_ids, input_lengths, spectrogram, spectrogram_lengths, audio_values loss

Prepare the exact tensors listed in the data contract before this step. Call model.validate_training_support() first, then follow the training workflow.

Checkpoints, provenance, license, and limitations

Property Value
Default checkpoint owensong/Inflect-Micro-v2
Hugging Face ID owensong/Inflect-Micro-v2
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.inflecttts.modeling_inflecttts.InflectTTSForTextToSpeech
Configuration voicehub.models.inflecttts.configuration_inflecttts.InflectTTSConfig
Source provenance voicehub/models/inflecttts/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.
