A first part uses a server-based automated speech recognizer. The second part is client-based automatic speech recognition (ASR) processing. Thus, techniques include a hybrid VDE solution that provides users with an accurate and flexible way to use speech recognition technologies. A server-based speech recognizer executes the open-search task, while a client-based recognizer refines the results from the server to deliver an optimized result. This system and method significantly improves recognition accuracy for dictation engine based POI search of Chinese Mandarin input and input from other languages. Moreover, the methods herein largely improve the user experience by allowing users to say a partial POI name, and abbreviation, or even say a POI name in a reversed word order."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for chinese point-of-interest search","description":"Techniques disclosed herein include systems and methods of automated speech recognition (ASR) for voice destination entry (VDE) include open voice searching (natural language searching) of destination","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8521539","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
