Disini akan diadopsi Sequential Minimal Optimization (SMO) untuk menangani data training yang besar. Pengukuran performansi dilakukan dengan perhitungan persentase error yaitu dengan SDER, NDER, dan OVER.Berdasarkan hasil pengujian, Support Vector Machine menunjukkan hasil yang baik untuk menangani VAD dengan jenis derau dan SNR yang bervariasi yaitu menghasilkan persentase error untuk SDER, NDER, dan OVER kurang dari 10 % untuk SNR lebih dari 0 dB.Kata Kunci : voice activity detection, klasifikasi, support vector machine, sequential minimal optimizationABSTRACT: Voice Activity Detection (VAD) is a detector that used to clasify signal into two periode, active speech and non-active speech. VAD has been implemented in various speech communication system to reduce transmission rate in the speech transmission. There are a lot of algorithmsto implement VAD, but most of them fail to classify when the noise increased.This final project will use Support Vector Machine classifier method with non-linier problem. Sequential Minimal Optimization (SMO) is adopted to solve the large training data. Performance measurement is done by calculating the error percentage like SDER, NDER, and OVER.From the experimental result, Support Vector Machine show a good result for VAD decision in the different noise and SNR level that is less than 10 % of error percentage of SDER, NDER, and OVER in more than 0 dB SNR levels.Keyword: voice activity detection, classification, support vector machine, sequential minimal optimizatio
