Methods to employ concatenation in asr service usage based on speech-to-text cost

Abstract

Systems and methods for processing audio streams are disclosed herein. In a disclosed method, N number of audio streams is received from an independent source, each audio stream includes speech content. A set of the N audio streams is concatenated to generate a concatenated audio stream. Based on the N received audio streams or the set of audio streams, N−1 or one less that the total number of audio streams in the set of audio stream separators, respectively, are generated. An audio stream separator is inserted between every two adjacent audio streams of the concatenated audio stream to generate a single audio stream payload. The single audio stream payload is transmitted for transcription of the audio stream speech content to text content and in response to transmitting the payload, a text file is received including text content corresponding to the audio streams delineated by the audio stream separators.
