Nos_Brais-GL: Galician TTS corpus

Galician TTS single-speaker corpus of approximately 18 hours of speech.

Nos_Brais-GL is based on a phonetically and morphosyntactically rich text corpus of 16,121 phrases (approximately 168,000 words) comprising three subcorpora: selected phrases from a corpus compiled by the Nós Project from multi-domain texts and previously used in the Nos_Celtia-GL TTS corpus; selected phrases from a previously compiled corpus created by the Grupo de Tecnoloxías Multimedia (GTM) and the Centro Ramón Piñeiro para a Investigación en Humanidades (CRPIH); and, finally, a 500-word phonetically rich single-word subcorpus extracted from the Dicionario de pronuncia da lingua galega.

Nos_Brais-GL was recorded in a controlled environment (recording studio) by a professional male voice talent selected among three speakers through a perceptual listening test in which 37 participants assessed the speakers' clarity, prosody, likeability, and language profiency.

Audio files are provided in a normalized audio version.

The file naming scheme of the audio files consists of a series of lowercase elements indicating the name of the voice (brais), and the type of audio (norm), followed by a 5-digit number identifying the utterance. All components are separated by hypens (e.g. brais-norm-00001.wav).

The dataset is divided in two splits, train (containing 16,100 sentences) and test (containing 21 sentences). All WAV files are in the audio directory, divided in subdirectories according to the corresponding split. The audio files are available in 16kHz 16-bit WAV, and amount to approximately 18 hours.
