A collection of speech samples to develop a verbal calculator

This collection is of speech samples of various words used in a calculator. Using this one can develop speech models for recognition or TTS purposes of words used in a calculator. Thus a voice-based calculator can be built with these samples and further tweaks of these samples. Here each word is only once recorded since my work with them involved further refinement of models by using the speech data later obtained from the user. So, it is a very tiny dataset, but useful for institutional and illustrational purposes, at least at the undergraduate level projects
