21. The method of claim 19 , wherein the speech processing environment comprises a speech processing software module.
19. A computer-implemented method for processing speech data in accordance with a privacy regulation, the method comprising: receiving, from a user device executing an entertainment application, a raw audio waveform that includes speech data of a user, wherein the raw audio waveform is recorded by the user device in response to the user interacting with the entertainment application; providing metadata and the raw audio waveform to a speech processing environment controlled by a third party for processing, where the metadata identifies a frequency component of a frequency representation of the raw audio waveform that is to be modified; directing the third party to perform an anonymization operation on the raw audio waveform before performing a speech processing operation, wherein the anonymization operation includes generating the frequency representation of the raw audio waveform, modifying the frequency component of the frequency representation that could be used to identify the user in order to produce a modified frequency representation, and generating an anonymized representation of the raw audio waveform from the modified frequency representation; allowing the third-party speech processing system to copy an element of the anonymized representation to improve future instances of speech processing; receiving, from the speech processing environment, a textual depiction of speech in the anonymized representation of the raw audio waveform; determining a responsive action for a synthetic character based at least in part on the textual depiction; and transmitting, to the user device, an instruction indicative of the responsive action for execution by the user device, wherein execution of the instruction causes the synthetic character to perform the responsive action within the entertainment application.
