To use the Java Speech API, a user must have certain minimum software and hardware available. The following is a broad sample of requirements. The individual requirements of speech synthesizers and speech recognizers can vary greatly and users should check product requirements closely.
· System requirements: most desktop speech recognizers and some speech synthesizers require relatively powerful computers to run effectively. Check the minimum and recommended requirements for CPU, memory and disk space when purchasing a speech product.
· Audio Hardware: Speech synthesizers require audio output. Speech recognizers require audio input. Most desktop and laptop computers now sold have satisfactory audio support. Most dictation systems perform better with good quality sound cards.
· Microphone: Desktop speech recognition systems get audio input through a microphone. Some recognizers, especially dictation systems, are sensitive to the microphone and most recognition products recommend particular microphones. Headset microphones usually provide best performance, especially in noisy environments. Table-top microphones can be used in some environments for some applications.
