    Abstract: An identity set may be selected from an identity pool of an identity management service. The identity set may be selected based on a threshold quantity of unnecessary permissions relative to one or more existing managed policies provided by the identity management service. The identity set may be grouped into a plurality of identity subsets. The grouping may be performed based at least in part on services accessed by the identity set. A plurality of candidate policies may be generated, such as by generating, for each identity subset of the plurality of identity subsets, based at least in part on a plurality of policy generation rules, a respective candidate policy. At least one candidate policy of the plurality of candidate policies may be selected as a new managed policy that is provided by the identity management service to users.

    Abstract: Voice customization is an application of voice synthesis that involves synthesizing speech having certain voice characteristics, and/or modifying the voice characteristics of human speech. Certain techniques for voice customization may be used in conjunction with compressing speech for storage and/or transmission. For example, speech may be received at a first device and transformed into a latent representation and/or compressed for storage and/or transmission to a second device. The system may use normalizing flows to transform the source audio to a latent representation having a desired variable distribution, and to transform the latent representation back into audio data. A flow model may conditioned using first speech attributes when transforming the source audio, and an inverse flow model may use second speech attributes when transforming the latent representation back into audio data. The first and/or second speech attributes may be modified to alter voice characteristics of the transmitted speech.
