Corpus de synthèse de parole NEMLAR
This corpus was produced within the NEMLAR project (http://www.nemlar.org). Two other resources, produced within the same project, are also available: NEMLAR Written Corpus (ELRA-W0042) and the NEMLAR Broadcast News Speech Corpus (ELRA-S0219).
The NEMLAR Speech Synthesis Corpus contains the recordings of 2 native Egyptian Arabic speakers (male and female, 35 and 27 years old respectively) recorded in a studio over 2 channels (voice + laryngograph). The recordings comprise more than 10 hours of data with transcriptions.
Speech samples are stored in 96 kHz, 24 bit with the least significant byte first (“lohi” or Intel format) as (signed) integers.
The speaker read 2,032 prompted sentences covering approx. 42,000 words in three categories: transcribed speech (6,600 words - 20%), written text (16,500 words - 50%), and constructed phrases (10,300 - 30%).
The transcribed speech consists of text from different domains, being produced in the Broadcast news task. The written text consists of news excerpts, novels and short stories with short sentences. Each paragraph is presented on a separate prompt sheet.
Constructed phrases consist of frequent phrases and diphone coverage sentences. The frequent used phrases are designed as derived from written text (article, news paper, etc.) and have been divided into six sub-domains:
• Frequently used colloquial expressions
• Consumer Information
The diphone coverage sentences cover the missing and rare diphones in all the data. To cover these diphones a large corpus about 150,000 words was used and from which the sentences were extracted.
The database is provided with orthographic, prosodic and phonetic transcriptions in SAMPA. All transcriptions are segmented at the utterance (sentence/command word) level, annotated at the word level and checked manually. A pronunciation lexicon including 3,589 headwords with phonetics in SAMPA is also available.
The database is distributed on 3 ISO 9660 DVD-ROM volumes. It has been validated by an external partner and a validation report is provided.
