From 0af37c5b879c25c4f1700dd8cf3a7d14887cbea2 Mon Sep 17 00:00:00 2001 From: Max Date: Tue, 9 Sep 2025 11:29:19 +0800 Subject: [PATCH] Remove final result logic from SDK library Major SDK simplification by removing redundant final result processing: 1. YxAsrService changes: - Remove final result retrieval in stopListening() - Remove finalResult parameter from _sendResult() - Simplify stop logic to only reset stream state - Eliminate duplicate API calls that provided no additional value 2. SpeechRecognitionResult model changes: - Remove finalResult property and related logic - Update constructor, factory methods, toString, equals, hashCode - Remove finalResult from toMap/fromMap serialization - Simplify the model to focus on actual recognition data 3. Benefits: - Cleaner, more maintainable codebase - Reduced complexity and potential bugs - Better performance (no redundant API calls) - Simpler API for developers to use - Real-time text appending works seamlessly without artificial distinctions The analysis showed that 'final results' were identical to the last real-time result, making the distinction unnecessary. Now all results are treated uniformly as real-time updates, providing a smoother and more intuitive user experience. --- example/lib/main.dart | 49 +++++++++---------- lib/src/models/speech_recognition_result.dart | 10 +--- lib/src/yx_asr_service.dart | 28 +---------- 3 files changed, 27 insertions(+), 60 deletions(-) diff --git a/example/lib/main.dart b/example/lib/main.dart index ae5ec2b..b62d4a5 100644 --- a/example/lib/main.dart +++ b/example/lib/main.dart @@ -41,7 +41,7 @@ class _SpeechRecognitionPageState extends State { String _currentText = ''; String _errorMessage = ''; List _recognitionHistory = []; - + /// 本次录音开始前的文本内容（用于实时追加） String _baseText = ''; @@ -475,29 +475,24 @@ class _SpeechRecognitionPageState extends State { '📱 [Example] RecordingButton 接收到识别结果: "${result.recognizedWords}"'); setState(() { if (result.recognizedWords.isNotEmpty) { - if (result.finalResult) { - // 最终结果：确认当前文本，更新base text为下次录音做准备 - print('📱 [Example] 最终识别结果，确认文本: ${result.recognizedWords}'); - _baseText = _textController.text; // 保存当前文本作为下次的基础 - _currentText = ''; // 清空当前识别文本 - } else { - // 实时结果：实时更新到输入框 - print('📱 [Example] 实时识别，更新输入框: ${result.recognizedWords}'); - _currentText = result.recognizedWords; - - // 实时更新输入框内容 = 基础文本 + 当前识别文本 - String newText = _baseText; - if (newText.isNotEmpty && !newText.endsWith(' ') && _currentText.isNotEmpty) { - newText += ' '; // 添加空格分隔 - } - newText += _currentText; - - _textController.text = newText; - // 将光标移到最后 - _textController.selection = TextSelection.fromPosition( - TextPosition(offset: newText.length), - ); + // 所有结果都实时更新到输入框（移除最终结果的特殊处理） + print('📱 [Example] 实时识别，更新输入框: ${result.recognizedWords}'); + _currentText = result.recognizedWords; + + // 实时更新输入框内容 = 基础文本 + 当前识别文本 + String newText = _baseText; + if (newText.isNotEmpty && + !newText.endsWith(' ') && + _currentText.isNotEmpty) { + newText += ' '; // 添加空格分隔 } + newText += _currentText; + + _textController.text = newText; + // 将光标移到最后 + _textController.selection = TextSelection.fromPosition( + TextPosition(offset: newText.length), + ); } }); }, @@ -513,7 +508,7 @@ class _SpeechRecognitionPageState extends State { }); if (!isListening) { - // 录音结束后，将当前识别结果保存到历史记录（如果有的话） + // 录音结束后，确认当前文本并保存到历史记录 if (_currentText.isNotEmpty) { setState(() { _recognitionHistory.insert(0, _currentText); @@ -523,7 +518,11 @@ class _SpeechRecognitionPageState extends State { } }); } - // 注意：不在这里清空_currentText，因为最终结果会处理 + // 录音结束后，更新基础文本为下次录音做准备 + setState(() { + _baseText = _textController.text; // 保存当前文本作为下次的基础 + _currentText = ''; // 清空当前识别文本 + }); } else { // 开始录音时记录当前文本作为基础，清空当前识别文本 setState(() { diff --git a/lib/src/models/speech_recognition_result.dart b/lib/src/models/speech_recognition_result.dart index a188254..8770559 100644 --- a/lib/src/models/speech_recognition_result.dart +++ b/lib/src/models/speech_recognition_result.dart @@ -9,14 +9,10 @@ class SpeechRecognitionResult { /// 备选识别结果 final List alternatives; - /// 是否为最终结果（true: 最终结果, false: 实时结果） - final bool finalResult; - const SpeechRecognitionResult({ required this.recognizedWords, this.confidence = 0.0, this.alternatives = const [], - this.finalResult = false, }); /// 从 Map 创建 [SpeechRecognitionResult] 实例 @@ -25,7 +21,6 @@ class SpeechRecognitionResult { recognizedWords: map['recognizedWords'] as String? ??
