Abstract:
A method of generating a number audio element for playing a desired number in an audio system, comprising:a) storing a plurality of audio elements used to represent a subset of the range of numbers; b) defining a plurality of match types used to determine if one or more matching audio element exists in the subset of the range of numbers; c) defining a plurality of accuracy prefixes representative of the error associated with any rounding of the desired number to be played; d) setting the accuracy prefix to a value representing an exact match between the desired number and a number audio element in the stored subset of audio elements representative of the range of numbers; e) filtering the audio elements to determine if an exact match exists; f) if an exact match does not exist, rounding the desired number to a pre-determined level of precision to create an estimated desired number; g) setting the accuracy prefix to a value representing the error associated with any rounding of the desired number to be played; h) filtering the audio elements to determine if an exact match exists between the estimated desired number and any of the plurality of audio elements used to represent a subset of the range of numbers; and i) repeating steps f)-g) until such time as an exact match has been determined between the estimated desired number and any of the plurality of audio elements used to represent a subset of the range of numbers.
