Digital cellular telecommunications system (Phase 2+); Universal Mobile Telecommunications System (UMTS); LTE; Speech recognition framework for automated voice services; Stage 1 (V13.0.0; 3GPP TS 22.243 version 13.0.0 Release 13)
"The present document defines the stage one description of the Speech Recognition Framework for Automated Voice Services. Stage One is the set of requirements for data seen primarily from the user""s and service providers"" points of view. This Technical Specification includes information applicable to network operators@ service providers@ terminal and network manufacturers. This Technical Specification contains the core requirements for the Speech Recognition Framework for automated voice services. The scope of this Stage 1 is to identify the requirements for 3G networks to support the deployments of a speech recognition framework - based automated voice services and therefore to introduce a 3GPP speech recognition framework as part of speech-enabled services. The Speech Recognition Framework for automated voice services is an optional feature in a 3GPP system."
