GL’s Speech Transcription Server (STS) is a PC-based automated speech-to-text conversion application. Among numerous applications, the Speech Transcription Server can be used for confirming voice prompts (announcements) and aid intesting Interactive Voice Response (IVR) systems as well as voice transportation over any network. Network providers use the application to record the voice prompts associated with the IVR, perform a Speech to Text conversion on the recording to confirm the prompt was proper (based on what the prompt should be), and thus confirming their IVR functioning. The application can be used to verify network quality as well as effect of different codecs on the speech quality.

This application works with GL’s File Conversion Utility which supports various industry standard codecs. This application can be good companion for GL’s MAPS™, and VQuad™ applications that allow transmission and recording of voice to/from audio files over many industry standards telecommunication networks such as VoLTE, UMTS, GSM, FXO, FXS, 4-Wire, ISDN, SS7, etc.

By incorporating GL’s Speech Transcription Server, MAPS™ IVR allows users to automate precise IVR tree traversal configurations through MAPS™ profiles and test for pass/fail conditions. IVR menus are divided into configurable prompts where certain keywords are expected. MAPS record each prompt for speech-to-text transcription and analyzes the transcribed text.

The Speech-to-Text application can also supplement GL’s Voice Quality Testing solution providing a more passive method to verify good quality audio. Using the VQT intrusive method for Voice Quality, the customer needs to send a pre-defined voice sample from near to far-side, record at the far-side and analyze based on the file sent from near-side. This is a very accurate method for generating a Voice Quality measurement but requires equipment at both ends of the call.

Alternatively, if access to both sides of the call is not available, the Speech-to-Text method can simply record a pre-specified sentence at the far-end and provide a Certainty score of the recorded Text based on what was expected. The Speech to Text conversion can confirm if the received audio, for instance a customer speaking into their phone, matches what was expected which would confirm there was relatively good audio on the network.
