Brief description

Scripted and semi-spontaneous human-human dialogs have been recorded in the acoustically-isolated room Nautilus with 48 kHz sampling frequency. Speakers uttered scripted, semi-spontaneous, and spontaneous speech and we controlled the absence of background noises. Interactions between speakers and their interlocutor (a recording assistant) are provided in separate mono files, accompanied by timestamps and tags that define the speaker's turns (emotional, neutral, question, etc.).

A total of 300 German speakers without marked accent have participated in the recording procedure. Subjective listening tests have been conducted to label semi-spontaneous speech according to 34 interpersonal speaker attributions (e.g. likable, attractive, friendly, competent, modest, childish, etc.) and to 34 naive voice descriptions (e.g. bright, creaky, articulate, melodious, etc.). In all, 140 independent labellers participated.

The speech files, associated labels, and speakers' metadata have been made available to the scientific community for non-commercial research and teaching purposes only.

We are open to any form of collaboration. Feel free to contact me under: laura.fernandezgallardo (at) tu-berlin.de
