Intended Uses

TTS and voice-cloning research
fine-tuning and adaptation experiments
benchmarking synthesis quality, stability, and robustness
speech enhancement and post-processing experiments
evaluation of expressive or long-form synthesis systems

Out-of-Scope Uses

impersonation of real people
fraud, deception, scams, or voice phishing
surveillance or biometric speaker identification
any use that misrepresents this dataset as natural human-recorded speech

License and Usage

This dataset is released under custom terms (license: other).

Permitted Use

You may use this dataset for:

research
non-commercial experimentation
benchmarking and evaluation
training or fine-tuning text-to-speech and voice-cloning systems
academic, educational, and personal projects

Attribution Requirement

If you use this dataset in a paper, model, demo, application, repository, benchmark, blog post, or derivative dataset, you must provide attribution.

Description: synthetic English speech dataset generated with VoxCPM2

Prohibited Use

You may not use this dataset for:

impersonation, fraud, deception, or voice phishing
generating misleading or non-consensual synthetic media
biometric identification, speaker surveillance, or identity verification of real people
unlawful, harmful, or abusive voice-cloning applications
redistributing the dataset as-is, or under a different name, without permission
representing the audio as human-recorded natural speech

Commercial Use

Commercial use is not permitted without separate written permission from the dataset publisher.

Nature of the Data

This dataset contains synthetic English speech, not human-recorded source speech. It is intended for TTS, voice-cloning, benchmarking, and related speech research. Users should evaluate suitability for their own use case and should not treat this dataset as a ground-truth corpus of natural human speech behavior.

Limitations

The reference prompt audio used during generation is not included in this release.
Synthetic audio quality and behavior reflect the strengths and weaknesses of the upstream generator and prompt setup.
This release is best understood as a synthetic training/evaluation resource, not as a substitute for carefully licensed natural speech corpora.
