Fonix unique concatenative speech synthesis approach can be applied to any language, and result in a high degree of naturalness. The company is open to negotiations for joint development of synthesizers for any language. The correct answer to this question depends on which soundbank is in question. 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.
