Asante Twi Bible Speech — Phonemes

Phoneme-labelled version of `ghananlpcommunity/asante-twi-bible-speech-text`, built for training a wav2vec2 (CTC) phoneme recogniser for Asante Twi.

Each example adds a phonemes column: a space-separated sequence of true Asante-Twi phonemes generated from the transcript with `twi-g2p` (vits output format).

Columns

—audio: 16 kHz mono audio
—text: original Twi transcript
—phonemes: space-separated phoneme target (the CTC label)

Why no alignments?

wav2vec2 is fine-tuned with CTC loss, which learns the alignment between audio frames and phoneme labels on its own. Training needs only (audio, phoneme-string) pairs — no forced-alignment timestamps.

Tokenizer

vocab.json (in this repo) maps each phoneme to an id for Wav2Vec2CTCTokenizer, including [PAD] (CTC blank) and [UNK].

Filtering

Transcripts containing digits, and any examples that produced an empty phoneme string, were dropped.
