  "account": "The article details the development of SayItVid, a real-time video pronunciation search engine that leverages authentic conversational video clips to provide synchronized subtitles, phonetic transcriptions, syllable stress markers, and word origins. The system consists of four main components: a video corpus, transcript ingestion, phonetic and IPA parsing, and a search engine index. It addresses the limitations of traditional online dictionaries, which provide static IPA strings that do not capture the nuances of conversational speech. SayItVid's pipeline includes calculating an acoustic context window around each token to provide a smooth viewing experience, converting dictionary entries into visual syllable stress markers, and indexing the data for fast retrieval. The article uses examples like inter-vocalic flapping to demonstrate the importance of video indexing over synthetic text-to-speech, showing that real-time video search provides a more natural and accurate pronunciation experience.",
  "summary": "SayItVid is a real-time video pronunciation search engine that addresses the limitations of traditional online dictionaries by indexing thousands of authentic conversational video moments and providing synchronized subtitles, IPA transcriptions, visual syllable stress markers, and word origins. The system breaks down the engineering architecture into four primary subsystems: video corpus ingestion, temporal word sync, phonetic & IPA parsing, and the search engine index. The ingestion process involves extracting timestamps from WebVTT and subtitle tracks, parsing sentence boundaries, and establishing word-level temporal anchors. Phonetic and syllable stress mapping aligns English lexicon tokens with international phonetic standards, parsing vowel nuclei to detect primary and secondary stress positions. The full-text inverted indexing enables fast retrieval of lexical phrases, collocations, and idioms using SQLite FTS5, while an interactive video player synchronization runtime binds video playback directly to subtitle cues and phonetic cards.",
