SpeechRecognizer.EmulateRecognizeCompleted Kejadian

Definisi

Ruang nama:

System.Speech.Recognition

Rakitan:

System.Speech.dll

Paket:

System.Speech v9.0.0-preview.4.24266.19

Sumber:

SpeechRecognizer.cs

Terjadi ketika pengenal bersama menyelesaikan operasi pengenalan asinkron untuk input yang ditiru.

public:
 event EventHandler<System::Speech::Recognition::EmulateRecognizeCompletedEventArgs ^> ^ EmulateRecognizeCompleted;

public event EventHandler<System.Speech.Recognition.EmulateRecognizeCompletedEventArgs> EmulateRecognizeCompleted;

member this.EmulateRecognizeCompleted : EventHandler<System.Speech.Recognition.EmulateRecognizeCompletedEventArgs> 

Public Event EmulateRecognizeCompleted As EventHandler(Of EmulateRecognizeCompletedEventArgs) 

Jenis Acara

EventHandler<EmulateRecognizeCompletedEventArgs>

Contoh

Contoh berikut adalah bagian dari aplikasi konsol yang memuat tata bahasa pengenalan ucapan dan menunjukkan input yang ditiru asinkron, hasil pengenalan terkait, dan peristiwa terkait yang diangkat oleh pengenal ucapan. Jika Pengenalan Ucapan Windows tidak berjalan, maka memulai aplikasi ini juga akan memulai Pengenalan Ucapan Windows. Jika Pengenalan Ucapan Windows berada dalam mode Tidur , maka EmulateRecognizeAsync selalu kembali null.

Keterangan

Setiap EmulateRecognizeAsync metode memulai operasi pengenalan asinkron. Recognizer memunculkan EmulateRecognizeCompleted peristiwa ketika menyelesaikan operasi asinkron.

Operasi pengenalan asinkron dapat meningkatkan SpeechDetectedperistiwa , , SpeechHypothesizedSpeechRecognitionRejected, dan SpeechRecognized . Peristiwa ini EmulateRecognizeCompleted adalah peristiwa terakhir yang dinaikkan oleh pengenal untuk operasi tertentu.

Saat Anda membuat delegasi untuk suatu EmulateRecognizeCompleted peristiwa, Anda mengidentifikasi metode yang akan menangani peristiwa. Untuk mengaitkan peristiwa dengan penanganan aktivitas Anda, tambahkan instans delegasi ke peristiwa. Penanganan aktivitas dipanggil setiap kali peristiwa terjadi, kecuali Jika Anda menghapus delegasi. Untuk informasi selengkapnya tentang delegasi penanganan aktivitas, lihat Peristiwa dan Delegasi.
