Key words: Automatic Speech Recognition Systems, Pronunciation Dictionary, Pronunciation Variation, Pronunciation Variation Modeling. Compared to the second method, a statistically significant decrement of 21%, 18% and 19% SER is measured in the third method for speaker2, speaker3 and speaker4 respectively. Using the acoustic evidence transcription of this speaker to the other three speakers has led to 12%, 17% and 19% SER for speaker2, speaker3 and speaker4 respectively. Using the third method for only one of the four speakers has led to a 6% SER which is a further decrement of 25% SER compared to the second method.
Compared to the first method, a statistically significant decrement of 8%, 8%, 7% and 6% SER is measured in the second method for speaker1, speaker2, speaker3 and speaker4 respectively. Ethiopia As the official language of Ethiopia, Amharic (also known as Abyssinian, Amarigna, Amarinya, Amhara, and Ethiopian) is spoken by more than 25 million people in Ethiopia and an additional 4 million emigrants abroad. The SER rates measured for the second method are 31%, 33%, 35% and 38% for speaker1, speaker2, speaker3 and speaker4 respectively. The SER rates measured for the first method are 39%, 41%, 42% and 44% for speaker1, speaker2, speaker3 and speaker4 respectively. Using the second and third methods has led to a larger improvement in SER compared to the benchmark first method. Type Amharic aims to improve your online experience when typing in. The third method is a grapheme based multiple pronunciation dictionary where the pronunciation variants are generated using data-derived approach. Alphabet TypeThe NATO phonetic alphabet international is the most widely used. Whats really great about Amharic is if you learn the sounds of each Fidel and if you spell or write a word correctly, you will be able to pronounce it. The pronunciation variants in the second method are generated using knowledge based approach. The second method is a grapheme based multiple pronunciation dictionary that contains alternate pronunciations for some of the words in the lexicon. The first method is a grapheme based canonical pronunciation dictionary that contains a single pronunciation for each word in the lexicon.
Ordinal numbers on the other hand tell the order of things and their rank: my first language is Amharic. It uses three methods to design Amharic pronunciation dictionaries. Numbers Grammar Rules Amharic cardinal numbers refer to the counting numbers, because they show quantity. This paper describes how the performance of a speaker dependent continuous Amharic speech recognizer is enhanced by modeling pronunciation variation. FUNDAMENTALS OF AMHARIC (REVISED EDITION), UNITS I-III (PRONUNCIATION AND LESSONS 1-15).
It is caused either by intra-speaker or inter-speaker variability. Pronunciation variation is one of the main factors that degrade the performance of Amharic ASRS.
