Abstract:In this paper we describe the 2005 AMI system for the transcription
of speech in meetings used for participation in the 2005 NIST
RT evaluations. The system was designed for participation in the speech
to text part of the evaluations, in particular for transcription of speech
recorded with multiple distant microphones and independent headset
microphones. System performance was tested on both conference room
and lecture style meetings. Although input sources are processed using
different front-ends, the recognition process is based on a unified system
architecture. The system operates in multiple passes and makes use
of state of the art technologies such as discriminative training, vocal
tract length normalisation, heteroscedastic linear discriminant analysis,
speaker adaptation with maximum likelihood linear regression and minimum
word error rate decoding. In this paper we describe the system performance
on the official development and test sets for the NIST RT05s
evaluations. The system was jointly developed in less than 10 months
by a multi-site team and was shown to achieve very competitive performance.
