9. A computing system, comprising: at least one processor; memory including instructions that, when executed cause the at least one processor to: receive text data; determine a first text segment of the text data, the first text segment including a first number of different phonetic units; determine a second text segment of the text data, the second text segment including a second number of different phonetic units; determine the first number is greater than the second number; send, based on the first number being greater than the second number, the first text segment to a first proofreader through a communications interface; receive feedback on the first text segment through the communications interface; add, based on the feedback, the first text segment to a text-to-speech (TTS) corpus, the TTS corpus comprising approved text segments; determine a third number of different phonetic units of the TTS corpus comprising the first text segment; determine the third number is less than a desired number of different phonetic units of the TTS corpus; and send, based on the third number being less than the desired number, the second text segment to a second proofreader through the communications interface.

The computing system of claim 9 , wherein the instructions further cause the at least one processor to: send a third text segment to a third proofreader through the communications interface; and determine a fourth number of different phonetic units of the TTS corpus comprising the first text segment and the third text segment.
