17. The one or more non-transitory computer-readable media of claim 13 , wherein the selecting comprises selecting the audio signal having a highest confidence value.
13. One or more non-transitory computer-readable media storing computer-executable instructions that, when executed by one or more processors, cause the one or more processors to perform acts comprising: receiving a plurality of audio signals that are focused respectively on different regions of an environment; analyzing the audio signals to recognize speech from each of the audio signals by concurrently generating a plurality of different text streams that each correspond to a different one of the audio signals; generating a confidence value for each of the plurality of different text streams corresponding to the audio signals by: comparing different text streams against each other to determine that a first text stream produces similar or identical results as a second text stream of the different text streams; and increasing a first confidence value associated with the first text stream based at least in part on the first text stream producing similar or identical results as the second text stream, wherein the confidence value for a particular text stream indicates an estimated accuracy of the recognized speech from the particular text stream; comparing confidence values generated for each of the plurality of different text streams associated with the different audio signals; and selecting one or more of the audio signals based at least in part on the comparing.
