Description

Sistemas fiveis de reconhecimento de voz by Nilashree Madakath, Sushama Wagh Estimated delivery 3-12 business days Format Paperback Condition Brand New Description Nos últimos anos, embora o reconhecimento do altifalante seja bastante promissor, a sua adoção generalizada tem sido dificultada por um desempenho insuficiente, marcado pela sua baixa precisão e por problemas de fiabilidade. No entanto, a resolução destes desafios é essencial para explorar plenamente as capacidades do reconhecimento biométrico da voz, com inquéritos que indicam a preferência pela biometria vocal. Em situações em que é utilizada a autenticação biométrica por voz remota, a manutenção da integridade dos vectores de caraterísticas cepstrais extraídos torna-se fundamental na presença de ruído de canal. Para melhorar a precisão do reconhecimento do locutor em aplicações remotas, é proposta uma nova abordagem em que são utilizados códigos LDPC (Low-Density Parity-Check) e códigos polares para o armazenamento e a transmissão de coeficientes cepstrais de frequência mel (MFCC) extraídos de amostras de voz. São descritos quatro métodos propostos e implementados que resultam em taxas de erro de bit mais baixas em canais ruidosos, bem como numa elevada taxa de exatidão para o sistema de reconhecimento remoto de altifalantes. Este livro conclui com a utilização sugestiva da codificação LDPC e Polar como parte integrante do reconhecimento remoto do locutor como parte do sistema de autenticação biométrica multimodal.

  1. Seller sent me the wrong book, but the book they sent sounded interesting enough for me to keep it. I still contacted the seller and communication was fast and professional. They apologized for sending me the wrong book and said I could return it for a refund. I told them that I liked the book they sent me and wanted to keep it. They were happy. Told them thank you and happy new year. People make mistakes, but the fact that this seller was quick and professional and apologized made a difference.

  2. The basket is perfectly what I ordered and as listed. It came in the factory packaging and was perfect upon delivery. Thank you postal service lol. The delivery took way longer than listed though, it was listed to come in a week from purchase, but took a whole month. I had some concerns at first, but communication with the company was top notch and they were very professional and answered most of my questions satisfyingly. Just prepare for a longer wait than listed, but I got what I bought lol.

  3. The two new out-of-print books I ordered were exactly as described and shipped promptly. I did ask the seller's support person (an AI chatbot, I think) to be sure to package the items carefully, and "he" said that he'd make that request of the shipping department. I knew this was hooey, and as I expected, the books were shipped in nothing but a padded paper mailer, no other protection. I got lucky, no damage, but don't bother making special requests of this seller.
