Speech to Equation Conversion using a PoE Tagger

Speech is being used increasingly to create documents. This is due to the availability of high-quality speech recognition software along with devices that capture speech signal ubiquitously. This has helped people to make best use of their time while performing non-productive activities such as commuting to & from work. Many solutions exist to convert dictations to text documents. However, there are very few solutions which can display a visual depiction of a spoken equation.In this paper, the authors propose a system that can take an audio signal containing an equation and convert it to its visual depiction. The authors make use of available 3rd party speech recognition system along with a proposed system for part of equation (PoE) tagging. The tokens and the PoE tags are used along with a set of pre-defined rules to create the equation sting used for emulation and display of the mathematical equation.
