This paper describes NaniBD, a set of tools designed for
transcribing and validating speech databases, developed at the
Signal Processing Group (GPS) of the Department of Signal
Theory and Communications of the Polytechnic University of
Catalonia (TSC/UPC). The main purpose of its development
was the need of a revision system in order to validate and
annotate the Spanish corpus of SpeechDat (II) in the speech
processing environment available at GPS. Despite of this,
NaniBD is designed as a general-purpose system that might fit
any other database, idiom or speech processing system. So far,
the system has been used to revise some 200,000 speech files
from three different corpora. In this paper we will focus our
attention to the actual implementation used in the transcription
of a SpeechDat (II) specifications compatible Catalonian corpus.
1000 speakers, each of them uttering 44 files, compose this
corpus. In this application, we use speech-noise detection,
automatic recognition of spontaneous prompts, digit and letter
to text translation and access to an external database in order to
minimise the amount of time spent by human operators in the
revision procedure.Peer ReviewedPostprint (published version)
