Providing speech-to-text (STT) transcription by a user endpoint device includes initiating an audio communication between an enterprise server and the user endpoint device, the audio communication comprising a voice interaction between a user associated with the user endpoint device and an agent associated with an agent device to which the enterprise server routes the audio communication; performing a first STT of at least a portion of the voice interaction to produce a first transcribed speech in a first language; concurrent with performing the first STT, performing, by the user endpoint device, a second STT of the at least the portion of the voice interaction to produce a second transcribed speech in a second language different than the first language, and transmitting the at least the portion of the voice interaction and at least the first transcribed speech from the user endpoint device to the enterprise server.
