Abstract: A computer assists in training a user to speak with a target accent by determining improvable aspects of diagnostic input of a user speaking diagnostic phrases with the target accent. The computer selects, a focus phrase characterized by at least one of said improvable aspects. The computer records performance input of the user attempting to say the focus phrase in the target accent. The computer converts the performance input into output having a baseline voice of the and the target accent applied. The computer presents the output and determines teachable aspects of revised performance input from the user replicating the output. The computer converts selected aspects of the revised performance input into augmented teaching output in the user's voice with the target accent applied. The computer presents the augmented teaching output to the user.

Abstract: Establishing a transfer mode between devices for large bulk records over a TLS protocol by fragmenting an encrypted bulk record into a set of pre-defined block sizes for convenient transfer. The pre-defined block sizes are specifically sized to indicate a beginning and an end of the transfer of the associated blocks making up the large bulk record. A middle box is unaware of the association between the blocks and permits transfer according to the maximum transmission unit of the transport layer security (TLS) protocol. The fragmented bulk record is reconstructed and decrypted for use after the transfer.
