############################################################################### <# .SYNOPSIS Transcribes an audio or video file to text. .DESCRIPTION Transcribes an audio or video file to text using the Whisper AI model. The function can handle various audio and video formats, convert them to the appropriate format for transcription, and optionally translate the output to a different language. Supports SRT subtitle format output and various audio processing parameters for fine-tuning the transcription quality. .PARAMETER FilePath The file path of the audio or video file to transcribe. .PARAMETER LanguageIn The language to expect in the audio. E.g. "English", "French", "German", "Dutch" .PARAMETER LanguageOut The language to translate to. E.g. "french", "german", "dutch" .PARAMETER SRT Output in SRT format. .PARAMETER PassThru Returns objects instead of strings. .PARAMETER UseDesktopAudioCapture Whether to use desktop audio capture instead of microphone input .PARAMETER WithTokenTimestamps Whether to include token timestamps in the output. .PARAMETER TokenTimestampsSumThreshold Sum threshold for token timestamps, defaults to 0.5. .PARAMETER SplitOnWord Whether to split on word boundaries. .PARAMETER MaxTokensPerSegment Maximum number of tokens per segment. .PARAMETER IgnoreSilence Whether to ignore silence (will mess up timestamps). .PARAMETER MaxDurationOfSilence Maximum duration of silence before automatically stopping recording. .PARAMETER SilenceThreshold Silence detect threshold (0..32767 defaults to 30) .PARAMETER CpuThreads Number of CPU threads to use, defaults to 0 (auto). .PARAMETER Temperature Temperature for speech recognition. .PARAMETER TemperatureInc Temperature increment. .PARAMETER Prompt Prompt to use for the model. .PARAMETER SuppressRegex Regex to suppress tokens from the output. .PARAMETER WithProgress Whether to show progress. .PARAMETER AudioContextSize Size of the audio context. .PARAMETER DontSuppressBlank Whether to NOT suppress blank lines. .PARAMETER MaxDuration Maximum duration of the audio. .PARAMETER Offset Offset for the audio. .PARAMETER MaxLastTextTokens Maximum number of last text tokens. .PARAMETER SingleSegmentOnly Whether to use single segment only. .PARAMETER PrintSpecialTokens Whether to print special tokens. .PARAMETER MaxSegmentLength Maximum segment length. .PARAMETER MaxInitialTimestamp Start timestamps at this moment. .PARAMETER LengthPenalty Length penalty. .PARAMETER EntropyThreshold Entropy threshold. .PARAMETER LogProbThreshold Log probability threshold. .PARAMETER NoSpeechThreshold No speech threshold. .PARAMETER NoContext Don't use context. .PARAMETER WithBeamSearchSamplingStrategy Use beam search sampling strategy. .PARAMETER SessionOnly Use alternative settings stored in session for AI preferences like Language, Image collections, etc. .PARAMETER ClearSession Clear alternative settings stored in session for AI preferences like Language, Image collections, etc. .PARAMETER PreferencesDatabasePath Database path for preference data files. .PARAMETER SkipSession Dont use alternative settings stored in session for AI preferences like Language, Image collections, etc. .EXAMPLE Get-MediaFileAudioTranscription -FilePath "C:\path\to\audio.wav" ` -LanguageIn "English" -LanguageOut "French" -SRT .EXAMPLE transcribefile
