BanglaKontho is a newly released 20‑hour single‑speaker Bangla text‑to‑speech corpus derived from professional audiobook recordings, comprising 7,050 segmented utterances with verified transcripts at 24 kHz. The project also provides a reusable Bangla text normalizer that handles Bangladeshi‑style digit grouping, currency and date expressions, Danda punctuation, and Unicode normalization, along with the full preprocessing pipeline. A baseline MB‑iSTFT‑VITS model trained from scratch on this corpus achieves a 9.5 % WER and 4.46 naturalness MOS, outperforming the same architecture retrained on the smaller 12‑hour IndicTTS‑Bn corpus.

The paper introduces a phoneme-guided text-to-speech (TTS) augmentation pipeline for automatic speech recognition (ASR) that links multilingual speech generation with candidate-text selection and reference-speech quality control. It proposes phoneme-frequency-guided selection (PFGS), which prioritizes candidate texts containing common phonetic content based on real ASR training transcripts. Experiments across four languages and 13 test sets show that random text selection improves recognition on 11 test sets, while PFGS further improves nine test sets with relative word error rate reductions up to 19.3%, and reference-speech filtering also contributes to performance gains.
