Harmonic Frontier Audio - Whisper and Aspiration (Preview Pack v0.9)

Harmonic Frontier Audio – Whisper and Aspiration (Preview, v0.9) A high-fidelity human vocal dataset designed for AI training, speech research, and expressive voice modeling. Whisper and Aspiration (Preview), created by Harmonic Frontier Audio, provides a compact reference set demonstrating the quality, formatting, and metadata conventions used in the Harmonic Frontier Audio Human Vocality Primitives series. 🔎 Summary This dataset provides high-quality, rights-cleared recordings of whisper phonation and aspiration-based vocal gestures — fundamental airflow-driven vocal behaviors that exist at the boundary between voiced speech and unvoiced breath noise. The recordings emphasize: airflow texture mouth shape variation fricative articulation transitions into and out of silence These characteristics make the dataset valuable for AI speech modeling, phonetics research, voice synthesis, breath modeling, and human-aligned vocal control systems. Developed by Harmonic Frontier Audio, this preview follows The Proteus Standard™ for dataset provenance, transparency, and ethical AI use.Learn more about the Proteus Standard → https://harmonicfrontieraudio.com/proteus-standard Full dataset details and licensing information are available at:https://harmonicfrontieraudio.com/datasets/whisper-aspiration If you find this dataset useful, please consider giving it a 🤍 on Hugging Face to help others discover it. 🌬️ About Whisper and Aspiration Whisper phonation occurs when air passes through the vocal tract without sustained vocal fold vibration, producing noise-shaped speech sounds rather than pitched phonation.Aspiration refers to breath-driven sound components that accompany or replace voiced articulation, including transitions into silence and near-noise airflow events. These phenomena are foundational to: speech production expressive voice synthesis breath-aware AI voice systems phonetic and physiological modeling This dataset presents a neutral, non-linguistic, non-performative representation of whisper and aspiration.It is not designed to encode semantic speech content, but rather to isolate acoustic primitives that underlie whisper-based vocal behavior. 📂 Contents Audio Files (.wav) Recorded at 96 kHz / 24-bit WAV format Exported as mono Fade-ins and fade-outs of 3–5 ms applied for consistency No compression, normalization, or creative processing applied High-pass filtered at ~40 Hz to remove subsonic rumble This preview includes 5 representative audio files, selected to demonstrate: sustained whisper phonation neutral and constrained mouth shapes fricative-based whisper gestures transitions into silence Metadata (.csv) Includes structured fields for: file name sound source type airflow type phonation type gesture and articulation descriptors microphone and recording chain sample rate, bit depth, and dataset version Metadata follows the Harmonic Frontier Audio – Foundations schema. 🎤 Recording Notes Recorded in a treated studio environment using a single-mic setup: Microphone: Rode NT1-A condenser microphone Recording chain: Rode NT1-A → Zoom F8n Pro Captured at 96 kHz / 32-bit float, rendered as 96 kHz / 24-bit mono WAV for release. Natural room tone and subtle breath noise were preserved to retain acoustic realism. ⚡ Usage This preview pack is designed for: Evaluation of Harmonic Frontier Audio dataset quality and structure Testing AI and DSP systems that model unvoiced or breath-driven sounds Research in phonetics, speech synthesis, and expressive vocal modeling Creative sound design involving breath, noise, and vocal texture 👉 Note: This is not a full dataset.The complete Whisper and Aspiration dataset includes a substantially larger set of whisper, aspiration, and airflow primitives and is available for licensing. 💡 Full Dataset Availability This is a preview pack of the Whisper and Aspiration Dataset.The complete dataset is available for commercial licensing.
