Ahoslabi was built within the frame of the RESTORE project (“Restauración, almacenamiento y rehabilitación de la voz”) and has received funding from Spanish Ministry of Economy and Competitiveness with FEDER support (RESTORE project, TEC2015-67163- C2-1-R), the Basque Government (PIBA-018-0035) and by the European Union's H2020 research and innovation program under the Marie Curie European Training Network ENRICH (675324)).

The database primarily consists of recordings of 31 laryngectomees (27 males and 4 females) pronouncing 100 phonetically balanced sentences. The total size of the recordings amount 10h48min for 1.16 Gb. Esophageal voices were recorded in a soundproof recording cubicle with a Neuman microphone. Additionally, it includes parallel recordings of the sentences by 9 healthy speakers (6 males and 3 females) to facilitate speech processing tasks that require small parallel corpora, such as voice conversion or synthetic speech adaptation. Apart from the sentences, the database also contains 4 sustained vowels and a small set of isolated words (14) which can be very valuable for research on esophageal speech analysis, diagnosis and evaluation.

Recordings are stored in WAV files, as sequences of 16 KHz Mono, 16 bits, Lo-hi (Intel), signed integer.

A pronunciation lexicon in SAMPA is also provided.

Restricted use: Due to the European Union General Data Protection Regulation (GDPR), the use of Ahoslabi is limited to European Union and countries providing adequate data protection as determined by the European Commission whose list is provided at the following link:
