This database contains parliamentary statements and newspaper reviews read by a semi-professional male speaker. It consists of a selection of 2150 sentences annotated and manually verified, including 100 rare phonemes in words. Prompts vary in length from 2.3 to 13.4 seconds, with an average length of 6.3 seconds. The recordings took place in an anechoic chamber using one table stand dynamic microphone (Rode NT1000). A 48 kHz sampling frequency and 16 bit resolution was used. The total duration of the recordings is 3.45 hours. The signal was automatically aligned with the transcription, and manually corrected using Praat speech analysis program. The database is phonetically annotated and manually corrected, which represents a lexicon of 11761 words with phonetic transcription. The package also includes a version of the speech database re-sampled at 16 kHz and edited. In all these files DC offset and the identified distortions which could affect the quality of speech synthesis were removed using High-pass filter. For a more detailed description, see “Oliver D.
