AppleWin emulates both the internal speaker (using the PC speaker or sound card) and also the Mockingboard sound card (using a PC sound card).
Use the AppleWin Configuration tab labelled Sound.
If you are using a sound card, then use at least DirectX-9.
You can select PC speaker or sound card:
When the Mockingboards are enabled, the cards are physically plugged into slots 4 and 5 of the Apple II.
Each Mockingboard is a type 'C': 2x AY8910 (3-channel sound generator) & 1x
SSI263 (speech chip)
Each AY8910 is fully emulated (tone, noise & envelope).
Each SY6522 (that controls an AY8910) can generate precise timer
interrupts or phoneme-complete interrupts.
Emulation of the SSI263 is basic at the moment and only plays back
phonemes at a fixed rate without any support for inflection or filters.
Additionally the Votrax/SC-01 (predecessor to the SSI263) is emulated by
remapping Votrax phonemes to the SSI263's.
When Phasor is enabled, the card is physically plugged into slot 4 of the Apple II.
Phasor is equivalent to 2 Mockingboards: so has 4x AY8910 & 1x SSI263.
There are a number of games and demos that support Mockingboard (or Phasor), eg:
