Speech Synthesis Solutions
|
Oki Semiconductor Speech Solutions offer a variety of products
that can be categorized in two main groups: Playback only and Record/Playback
devices.
Playback-only devices offer flexibility in terms of memory
needs. There are devices available with internal memory (Mask ROM, P2ROM, Flash,
OTP) and those that support external memory only.
Mask ROM devices are mainly targeted for high-volume
applications that can benefit from low cost achieved by large-scale production
quantities.
P2ROM devices offer advantages similar to Mask ROM devices, but
without the requirement for high-volume production. In addition, since there is
no need for mask creation, the turn around time after modifying content is a lot
shorter than Mask ROM devices.
Flash and OTP devices are targeted to small-volume applications
or where there is a need to customize the playback content on a constant
basis.
Record/Playback devices support only recording to external
memory, thus the amount of recording time is constrained only by the amount of
external memory allocated for such purpose.
