Speech chip is a digitalker MM54104, 100% certain of it. The wavefile shows the distinctive half-period zeroing. The voice roms are already dumped, they're at 32_a3.6e, 32_a2.6d and 32_a1.6c, concatenated in that order. There are 45 words, most if not all of which are from the standard national semiconductor SSR1/SSR2 set.
Notes
note 1 = (one EPROM is not dumped, but should be identical to set 1
