1. A computer-implemented method, comprising: receiving, at a computing device having one or more processors, a first set of digital audio signals; comparing, at the computing device, a signal amplitude of the first set of digital audio signals to a first threshold; when the signal amplitude of the first set of digital audio signals exceeds the first threshold: obtaining, at the computing device, a first translation of the first set of digital audio signals from speech of a first language into translated speech of a second language, and outputting, at the computing device, the first translation; and when the signal amplitude of the first set of digital audio signals does not exceed the first threshold, comparing the signal amplitude of the first set of digital audio signals to a second threshold, and when the signal amplitude of the first set of digital audio signals exceeds the second threshold: obtaining, at the computing device, a second translation of the first set of digital audio signals from speech of the second language into translated speech of the first language, and outputting, at the computing device, the second translation.
