GL Communications Announces Speech Transcription Server

GL Communications Inc. has announced its new speech-to-text conversion utility referred to as Speech Transcription Server.

GL’s Speech Transcription Server (STS) is a Speech-to-Text conversion application that enables the translation of spoken language into text along with analysis of the transcribed speech. This application can be used for confirming voice prompts, testing Interactive Voice Response (IVR) and Voice Mail (VM) systems, as well as voice transmission over any network.  STS supports REST APIs which allows the utility to be used with other GL’s intrusive test tools such as MAPS™ and VQuad™ . One can send and receive transcription requests, as well as retrieve transcription results from database.

MAPS™ provides a unique architecture for multi-interface, multi-protocol simulation, which make it suitable for testing any core network, access network and inter-operability functions. VQuad™ Probe HD is an all-in-one self-contained hardware supporting multiple physical interfaces for connecting to practically any wired or wireless network while automatically performing end-to-end voice and data testing over any network”, he said.

STS can also be used with GL’s Voice Quality Testing solution to measure network voice quality, effect of different codecs on speech transcription quality, effect of noise, echo, and bit error rate. STS supports various industry standard voice codecs – refer to Voice Codec webpage for more details.”
