處理收到的 Amazon Chime SDK 即時轉錄事件

下列範例示範如何處理收到的 TranscriptEvent。

範例 1：StartMeetingTranscription

此範例顯示典型StartMeetingTranscription的操作。

meeting.StartMeetingTranscription(
    { EngineTranscribeSettings: { Languagecode: ‘en-US’ } } ); 

操作會產生 TranscriptEvent。

{   
    status: {        
        type: 'started',        
        eventTimeMs: 1620118800000,        
        transcriptionConfig: {                    
            LanguageCode: 'en-US'        
        }    
    }
} 

範例 2：部分轉錄結果

在這個範例中，出席者說：「快速的棕色狐狸跳過鬆散的狗。」 請注意，在此範例中，isPartial值為 true。如果您深入查看訊息，您可以看到系統將「fox」一詞處理為「facts」。系統會使用相同的 resultId 來更新文字記錄。

{
    transcript: {
        results: [{
            resultId:"1",                               isPartial: true,
            startTimeMs: 1620118800000,                 endTimeMs: 1620118801000,
            alternatives: [{
                items:[{
                    type:        'pronunciation',
                    startTimeMs: 1620118800000,         endTimeMs: 1620118800200,
                    attendee: { attendeeId: "1",        externalUserId: "A"},
                    content: "the",                     vocabularyFilterMatch: false
                },
                {
                    type:        'pronunciation',
                    startTimeMs: 1620118800200,          endTimeMs: 1620118800400,
                    attendee: { attendeeId: "1",         externalUserId: "A" },
                    content:"quick",                     vocabularyFilterMatch: false
                },
                {
                    type:'pronunciation',
                    startTimeMs: 1620118800400,          endTimeMs: 1620118800750,
                    attendee: { attendeeId: "1",         externalUserId: "A" },
                    content:"brown",                     vocabularyFilterMatch: false
                },
                {
                    type:'pronunciation',
                    startTimeMs: 1620118800750,          endTimeMs: 1620118801000,
                    attendee:{ attendeeId: "1",          externalUserId: "A" },
                    content:"facts",                     vocabularyFilterMatch: false
                },
                {
                    type:'punctuation',
                    startTimeMs: 1620118801000,          endTimeMs: 1620118801500,
                    attendee:{ attendeeId: "1",          externalUserId: "A" },
                    content:    ",",                     vocabularyFilterMatch: false
                }]
            }]
        }]
    }
}

範例 3：最終轉錄結果

發生部分文字記錄時，系統會再次處理該片語。此範例isPartial的值為 false，且訊息包含「fox」而非「facts」。系統會使用相同的 ID 重新發出訊息。

{
    transcript: {
        results: [{
            resultId:"1",                                isPartial: false,
            startTimeMs: 1620118800000,                  endTimeMs: 1620118801000,
            alternatives: [{
                items:[{
                    type:        'pronunciation',
                    startTimeMs: 1620118800000,          endTimeMs: 1620118800200,
                    attendee: { attendeeId: "1",         externalUserId: "A"},
                    content: "the",                      vocabularyFilterMatch: false
                },
                {
                    type:        'pronunciation',
                    startTimeMs: 1620118800200,          endTimeMs: 1620118800400,
                    attendee: { attendeeId: "1",         externalUserId: "A" },
                    content:"quick",                     vocabularyFilterMatch: false
                },
                {
                    type:'pronunciation',
                    startTimeMs: 1620118800400,          endTimeMs: 1620118800750,
                    attendee: { attendeeId: "1",         externalUserId: "A" },
                    content:"brown",                     vocabularyFilterMatch: false
                },
                {
                    type:'pronunciation',
                    startTimeMs: 1620118800750,          endTimeMs: 1620118801000,
                    attendee: { attendeeId: "1",          externalUserId: "A" },
                    content:"fox",                       vocabularyFilterMatch: false
                },
                {
                    type:'punctuation',
                    startTimeMs: 1620118801000,          endTimeMs: 1620118801500,
                    attendee: { attendeeId: "1",          externalUserId: "A" },
                    content:    ",",                     vocabularyFilterMatch: false
                }]
            }]
        }]
    }
}
