13. One or more non-transitory computer-readable storage media storing instructions that, when executed by one or more processors, communicatively coupled to a communication network, configure the one or more processors to perform acts comprising: receiving, by a computer-based speech recognition system, a speech input including one or more words or phrases, wherein the speech input is from a call to a call center via the communication network; determining, by the computer-based speech recognition system, to provide the speech input to a human; receiving a response from the human that identifies a first task for the speech input, the first task including a first transcription of the speech input; processing the speech input to identify a second task for the speech input, the processing using a set of internal representations of the computer-based speech recognition system, the set of internal representations comprising one or more machine-readable parameters for recognizing speech in a speech utterance, the second task including a second transcription of the speech input; comparing the speech input and the first transcription of the speech input included in the first task with the second transcription of the speech input included in the second task, the set of internal representations comprising one or more machine-readable parameters for recognizing speech in a speech utterance; modifying the set of internal representations of the computer-based speech recognition system based at least in part on the comparing the first transcription with the second transcription to create a modified set of internal representations, wherein the modifying includes adjusting at least a portion of the set of internal representations; checking the performance of the modified set of internal representations to prevent the modification from degrading the set internal representations, wherein the checking comprises determining that a performance difference between the set of internal representations before and after modification is within a margin of error; receiving, by the computer-based speech recognition system, another input; and processing, by the one or more processors and based at least in part on the modified set of internal representations, the other input to identify a third task for the other input.
17. The computer-based speech recognition system of claim 13 , wherein: the speech input comprises a speech utterance.
