![]() A few speech recognition engines still need a DSP (digital signal processor) card. Almost any sound card will work for speech recognition and text-to-speech, including Sound Blaster? Media Vision? ESS Technology, cards that are compatible with the Microsoft?Windows Sound System, and the audio hardware built into multimedia computers. ![]() On the average, speech recognition for dictation consumes 4 to 8 megabytes (MB) of random-access memory (RAM) for discrete dictation and about 32 megabytes for continuous dictation in addition to that required by the running application. The speech recognition and text-to-speech engines currently on the market typically require a Pentium 60 or faster processor for discrete dictation and a Pentium 200 or faster processor for continuous dictation. These hardware and software requirements should be considered when designing a speech application: Not all computers have the memory, speed, microphone, or speakers required to support speech, so it is a good idea to design the application so that speech is optional. Speech Recognition - Dictation Hardware and Software RequirementsĪ dictation application requires certain hardware and software on the user's computer.
