refactor: Extract logic as AudioData.from_file()

[ftnext]

Delete boilerplate code as refactoring first step

[Copilot]

Pull Request Overview

This PR refactors audio file processing to eliminate repetitive boilerplate code by introducing the class method AudioData.from_file(), simplifying how audio files are loaded across the codebase.

• Extracts common audio file loading logic into AudioData.from_file() in speech_recognition/audio.py.
• Replaces duplicate code that creates a Recognizer, opens an AudioFile, and records audio with a single, convenient method call.
• Updates examples, recognizers, and tests to use the new from_file() method.

speech_recognition/recognizers/whisper_local/faster_whisper.py:101

• Replacing r.listen with sr.AudioData.from_file changes the behavior from using r.listen to using r.record internally. Confirm that this change is intentional since it may alter how the audio data is captured.

audio_data = sr.AudioData.from_file(args.audio_file)

speech_recognition/recognizers/whisper_api/openai.py:73

• Switching from r.listen to sr.AudioData.from_file (which uses r.record) could change the audio capture behavior. Verify that this behavior change aligns with the intended functionality for file-based audio input.

audio_data = sr.AudioData.from_file(args.audio_file)
