News bulletins in the upper valaisan german dialect, broadcast by RRO (radio rottu oberwallis), taken from their web site and annotated at Idiap.
The database was collected during the summer of 2013 as a sub-project of the IM2 NCCR www.im2.ch
The purpose was to investigate building speech recognition and synthesis technology in walliserdeutsch. As well as tying into a general Idiap focus towards Swiss languages, it was also done with the Valais*Wallis Digital project, and the 2015 celebrations, in mind. The data from radio rottu was used as it was, to our knowledge, the only substantial source of walliserdeutsch available. The transcriptions were taken from radio rottu source for the spring of 2013, but transcribed directly from the audio for other data.
