The 16-bit Linear soundbank, the largest of the Fonix soundbanks, requires approximately 310 Mb of disk space. If the 16-bit linear soundbank is installed, the necessary free hard disk space increases to 310 megabytes. Synthesis speed is system-dependent. For example, on a Pentium II 233 MHz running Windows NT with 128 MB of RAM, it averages 114 words per second. The synthesis rate will be less on a slower machine or a machine with less memory.
Memory does have an impact on the performance of the system if multiple channels are used.
An increase in channels results in a decrease in synthesized words per second. The part of speech of individual words can be changed with a tag. Since the Synthesizer is sensitive to punctuation marks, the rhythm of the output can be altered by adding commas, colons, periods, question marks, etc. The system is based around a vocabulary of over 100,000 words, but it is able to pronounce many more than that. These formats can be used on a Sound Blaster 16 sound card or any Dialogic card.
