title: Harmonic Frontier Audio - Plosives and Non-Lexical Consonant Bursts (Preview Pack v0.9)

description: Harmonic Frontier Audio -- Plosives and Non-Lexical Consonant Bursts (Preview, v0.9)

A high-fidelity human vocal dataset designed for AI training, speech research, and articulation-aware voice modeling.

Plosives and Non-Lexical Consonant Bursts (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 plosive articulations and short-duration non-lexical consonant burst gestures --- discrete vocal events produced through controlled vocal tract closure and rapid release.

The recordings emphasize: - articulatory closure and release - transient airflow dynamics - burst intensity and envelope shape - non-linguistic consonant gestures

These characteristics make the dataset valuable for AI speech and voice modeling, phonetics research, articulation-aware synthesis, onset 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

  🫁 About Plosives and Non-Lexical Consonant Bursts

Plosives are produced by complete or near-complete closure of the vocal tract followed by a controlled release of air pressure, resulting in a short, high-energy acoustic burst.Non-lexical consonant bursts refer to similar transient gestures produced without linguistic intent or semantic content.

These vocal behaviors are foundational to: - speech articulation and onset modeling - expressive and controllable voice synthesis - articulation-aware AI systems - phonetic and physiological research

This dataset presents a neutral, non-linguistic, non-performative representation of plosive and consonant burst gestures.It is not designed to encode semantic speech content, but rather to isolate gesture-level acoustic primitives underlying consonant articulation.



  📂 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 ~60 Hz to reduce proximity effect and subsonic rumble


This preview includes 3 representative audio files, selected to demonstrate: - clean pulmonic egressive plosive articulation - contrasting non-lexical consonant burst gestures - variation in burst intensity and release character



  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 and is a strict subset of the full production metadata.



  🎤 Recording Notes



Recorded in a treated studio environment using a single-mic setup:



Microphone: RØDE NT1-A condenser microphone

Recording chain: RØDE NT1-A → Zoom F8n Pro



Captured at 96 kHz / 32-bit float, rendered as 96 kHz / 24-bit mono WAV for release.

Natural transient dynamics were preserved to maintain articulatory realism




  ⚡ Usage

This preview pack is designed for:



Evaluation of Harmonic Frontier Audio dataset quality and structure\
