The Italian Speech Corpus 1 contains the recordings of 202 native Italian speakers (112 males, 90 females) recorded in an office and a closed public place, over 4 channels, in a range of low to medium background noise environments (Plantronics Audio 10 (computer/desk mic), Shure SM58 (desk mounted dynamic mic), Shure Beta 53 (headset mic) and Andrea DA-400 (array mic)). The data collection and transcription were performed by Appen (Australia). Speech samples are stored as sequences of 16-bit 22.05 kHz PCM in uncompressed WAV files. Each speaker read the following items (prompted): - 100 command words - 100 phonetically rich sentences The following age distribution has been obtained: 22 speakers are between 18 and 19, 141 are between 20 and 30, 34 are between 31 and 45, and 5 are between 45 and 60. Information about the speakers? place of birth is included. The database is provided with orthographic transcriptions in SAMPA, including canonical and alternative pronunciation, and syllable, stress and acoustic events markings. All transcriptions were segmented at the utterance (sentence/command word) level, annotated at the word level and checked manually. A pronunciation lexicon including 7,300 headwords (plus variants) is also available. This database is aimed to be used within speech recognition and voice control applications.
