The full dataset encompasses: - short, forceful exertion exhales - sustained strained phonation under simulated physical load - non-lexical effort grunts with compressed airflow and abrupt onsets - continuous load-onset transitions with gradually increasing effort - low- and mid-register conditions - light exhale anchors without elevated tension for comparative reference - controlled variations in thoracic pressure, phonatory tension, and airflow resistance These characteristics make the dataset valuable for **AI speech and voice modeling**, **expressive audio generation**, **effort-aware synthesis**, **phonetics research**, **embodied-agent audio**, **physical-state modeling**, and **human-aligned vocal control systems**. Developed by **Harmonic Frontier Audio**, this preview follows *The Proteus Standardβ„’* for dataset provenance, transparency, and ethical AI use.

These sounds can range from unvoiced forceful exhalations to compressed grunts and sustained voiced gestures produced with increased tension and restricted airflow. The dataset also captures **load-onset transitions**, in which phonatory tension and airflow resistance increase gradually over a continuous gesture, together with light exhale anchors that provide low-effort baseline comparisons. These phenomena are foundational to: - effort- and physical-state-aware voice synthesis - non-lexical human sound generation - embodied and multimodal agent behavior - phonatory tension and airflow-resistance modeling - physiological and expressive audio research - modeling acoustic transitions from low effort to increased physical load This dataset presents a **neutral, non-linguistic representation** of effort and exertion vocal behavior. It is not designed as dramatic acting, shouted performance, or semantic speech, but rather to isolate **acoustic primitives** associated with physical effort, strained airflow, compressed vocal gestures, and changing load. --- ## πŸ“‚ 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 **3 representative audio files**, selected to demonstrate: - a **low-register exertion exhale** β€” a short, forceful airflow release associated with physical exertion and increased thoracic pressure - a **low-register effort grunt** β€” a non-lexical burst characterized by compressed airflow and an abrupt onset - a **mid-register load-onset transition** β€” a continuous gesture with gradually increasing phonatory tension and airflow resistance associated with simulated physical effort --- ### 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 β†’ Zoom F8n Pro - Captured at **96 kHz / 32-bit float**, rendered as **96 kHz / 24-bit** mono WAV for release. - Performer positioned approximately **3.5 inches from the microphone**, with the microphone approximately **10–15 degrees off-axis**. - Burst gestures were recorded at approximately **1–2 seconds**, sustained conditions at **5–7 seconds**, and transitions at **6–8 seconds**. - Exact pitches were not prescribed; performances were organized by **low and mid register zones**. - Physical effort was simulated through controlled muscular and core engagement while avoiding theatrical exaggeration, shouting, and lexical content. --- ## 🌈 Spectrogram Preview Below is a spectrogram illustrating the concentrated transient energy, compressed airflow signatures, changing phonatory tension, and intensity contours characteristic of exertion exhales, effort grunts, and load-linked vocal transitions: ![Spectrogram Preview](Spectrogram_Preview.png) ## ⚑ Usage This preview pack is designed for: - Evaluation of Harmonic Frontier Audio dataset quality and structure - Testing AI and DSP systems that model exertion, physical effort, strained airflow, and non-lexical vocal behavior - Research in phonetics, expressive voice synthesis, embodied audio, and physiological sound modeling - Creative and technical applications requiring controlled effort-linked vocal and respiratory primitives πŸ‘‰ **Note:** This is **not a full dataset**.
