14. A system for enabling training of an acoustic model, the system comprising: a shredding module configured to shred a speech corpus dynamically to produce text segments and depersonalized audio features corresponding to the text segments, the depersonalized audio features including filtered audio data remaining after speaker vocal characteristics and other audio characteristics have been removed, the speech corpus comprising a plurality of messages that each contain audio and corresponding text content, the shredding splitting each of the plurality of messages into strips, each strip comprising text segments and corresponding depersonalized audio features; the shredding module further configured to mix up the strips of the text segments and corresponding depersonalized audio features to produce strips mixed up in randomized order; and an enabling module configured to enable a system to train an acoustic model using the strips mixed up in randomized order.
