TIMITPhones: TIMIT Phoneme Dataset

This corpus is a phoneme‑level derivative of the original TIMIT Acoustic‑Phonetic Continuous Speech Corpus.
Each entry pairs a 1‑second waveform excerpt with a single phoneme label taken from the 61‑phone TIMIT inventory (the mapping to 39‑phone and broad‑class sets is also provided).

This version is designed for quick prototyping of phoneme classifiers or probing acoustic representations.

Supported Tasks and Leaderboards

• Automatic Speech Recognition (phoneme classification)
• Representation Probing (e.g. evaluate SSL acoustic models)

Languages

• American English (predominantly GenAm, multiple dialects represented).

Source Data

The source material is the licensed TIMIT corpus (LDC93S1). Waveforms were segmented to align with individual phone boundaries using the provided .PHN time‑marks.

Annotations

Phoneme boundaries originate from the manual TIMIT annotations. No additional human annotation was performed.
