I would look seriously at the adaptive (ADPCM) voice handling chips from OKI Semiconductor. An 8051 can easily feed these low cost chips with data at low rates to achieve fairly good quality sound. You can easily anticipate holding 30 minutes or more of voice type data in modern flash chips of a couple of mega bytes. The flash can be attached as XRAM to the 8051 external bus and managed via bank switching from some additional port pins.
