This sound is from Akemi (Blue Eye Samurai) TTS Computer AI Voice

Akemi is the daughter of the samurai lord Tokunobu Daichi, who is bound by the traditional ways of her society. When necessary she becomes the soft-spoken, deferential, traditional-sounding daughter her father expects her to be. With those she trusts, she can be herself: smart, succinct, and determined, speaking in a stronger lower register.
