<p>PURPOSE:To reduce input errors, by executing an input by a key corresponding to a phoneme symbol, and also limiting a range of the next phoneme key to be inputted, in accordance with occurrence probability between phoneme strings to be inputted. CONSTITUTION:When a phoneme string is inputted through a phoneme corresponding key corresponding by 1 to 1 to each phoneme on a keyboard circuit 2, and is outputted through a phoneme data transmission line 3, an input phoneme limiting data generating circuit 4 generates a phoneme data whose input is impossible, by referring to a phoneme which has been inputted in the past, and outputs it to the keyboard circuit 2. As for the key corresponding to the phoneme data whose input is impossible, the keyboard circuit 2 does not output phoneme data to the transmission line 3 even if the key is depressed. On the other hand, a phoneme symbol/mark symbol converting circuit 7 generates a symbol train corresponding to the phoneme string, by referring to a phoneme symbol/mark symbol table 9, and outputs it through a mark symbol output terminal 8.</p> |
