Spelling error has become an error that is often found in this era which can be seen from the use of words that tend to follow trends or culture, especially in the younger generation. This study aims to develop and test a detection and identification model using a combination of Bigram Vector and Minimum Edit Distance Based Probabilities. Correct words from error words are obtained using candidates search and probability calculations that adopt the concept of minimum edit distance. The detection results then identified the error type into three types of errors, namely vowels, consonants and diphthongs from the error side on the tendency of the characters used as a result of phonemic rendering at the time of writing. The results of error detection and identification of error types obtained are quite good where most of the error test data can be detected and identified according to the type of error, although there are several detection errors by obtaining more than one correct word as a result of the same probability value of these words.

This study aims to describe the intonation perception of the Malay aristocrats' speech on emotions.

This study describes the Langkat Malay (LM)'s intonation in two emotional utterances, i.e., anger and happiness. Those two are especially practiced by the nobles (Nb) and the common people (CP) in Tanjungpura District which is administratively located in Langkat Regency, North Sumatra Province (Indonesia). It involves six main informants for obtaining key speeches and 40 respondents for perception tests. This study uses acoustic phonetics theory and Praat program. For the emotional speech of anger the expression is pedeh hati ambe ngeleh kelakuannya tang orang tua which are used by both the Nb and the CP and can be phonetically pronounced as [pədeh ha:tɪ ʌmbə ŋəleh kəlʌkʊanɲʌ tʌŋ ɔːrʌŋ tʊa]; while for the emotional speech of happiness the expression is senang bena amba mendengar kabarnya yo which is pronounced as [sənʌŋ bena: ʌmbə məndəŋa:r kʌbʌrɲʌ jo] and this last expression is only spoken by the Nb. The study is conducted with several steps. The initial step refers to the process of digitization and the next was to measure the acoustic characteristics of frequency and duration of speeches, and extracting the measurement results. The final steps was the statistical tests to determine the acoustic characteristic significance of measurement results. The findings of the study are that intonation patterns, frequency and duration, and speech intonation are all signified in the characteristics of LM's utterances. Intonation pattern of anger among the CP tends to have the falling movement with declining tone contour; while among the Nb the pattern shows to rise and fall with declining tone contour. Furthermore, there was no distinction of intonation pattern of sadness among the CP and the Nb because they emphasizes the decliningtone contour. Finally, the intonation pattern of happiness exhibits a rise among the Nb and a rise-fall among the CP; however, both the Nb and the CP indicate the inclining tone contour.
