banc-trawsgrifiadau-bangor-translations

English translations of the verbatim Welsh sentence column of techiaith/banc-trawsgrifiadau-bangor, produced with the techiaith/bergamot-mt-cy-en tiny on-device cy→en student model.

Each Welsh sentence is translated twice:

1. translated-verbatim — the raw verbatim speech transcription is translated as-is.
2. translated-normalized — the Welsh is first normalized into standard written Welsh with the techiaith-speech-normalizer, then translated.

The goal is to measure what difference Welsh speech normalization makes to the downstream English translation.
