Frequency Analisys of Speech Signals for Devanagari Script and Numerals Using FFT

Abstract: This paper contains the frequency analysis of spoken Devnagari script and Numerals from the original speech signals. Devnagari vowels and numerals are playing the vital role in pronunciation of any word or counting. Each vowel & number is classified as starting, middle and end according to the duration of occurrences in the word. The Devnagari script having 12-vowels and 34-consonants are used in some Indian language like Hindi and 10 numerals (0-9) are used in mathematics. Sound samples from multiple speakers were utilized to extract different features. Initial processing of data, i.e., normalizing and time-slicing was done using a combination of Simulink and MATLAB. Afterwards, the same tools were used for calculation of Fourier descriptions and correlations. The correlation allowed comparison of the same words or numeral spoken by the same and different speakers. So the frequency has been calculated in statistical manner and generates a table between amplitude and frequencies. Mean and standard deviation such a system can be potentially utilized in implementation of a voice-driven help setup at call centres of commercial organizations operating in India and other foreign region. The implementation, experiments and result discussions are also existence.

Issues in Bahing orthography development

Abstract: Section 1 of this paper summarizes the community-based process of Bahing orthography development. Section 2 introduces the criteria used by the Bahing community members in deciding how Bahing sounds should be represented in the proposed Bahing orthography with Devanagari used as the script. This is followed by several sub-sections which present some of the issues involved in decision-making, the decisions made, and the rationale for these decisions for the proposed Bahing Devanagari orthography: Section 2.1 mentions the deletion of redundant Nepali Devanagari letters for the Bahing orthography; Section 2.2 discusses the introduction of new letters to represent Bahing sounds that do not exist in Nepali or are not distinctively represented in the Nepali Alphabet; Section 2.3 discusses the omission of certain dialectal Bahing sounds in the proposed Bahing orthography; and Section 2.4 discusses various length related issues.

Investigating Frequently Used Stroke Sequence, of Handwritten Devanagari Letters, by Observing Second Script Learners

Abstract: Eleven scripts are used in multilingual India today However, not enough research is found in the domain of handwriting acquisition In this study, we investigate Devanagari handwriting activity by observing its second script learners A text paragraph containing basic Devanagari letters, numbers and few consonant clusters, is given to a selection of students, who have learnt Devanagari as the second script This activity is captured using a movie camera A similar activity is conducted on a student who has learnt Devanagari as the first script We separate key letters from the scanned manuscript for observation of shape and stroke sequence To observe the direction and sequence of strokes, we separate video clips of key letters In this paper, we present a detailed analysis of the key letter ‘Ka’ It is observed that second script learners exhibit a variety in the types of stroke sequences used to produce the letter Cross-checking the stroke sequence in a prescribed school book, provides us insights on the ideal stroke sequence
