Audio and Video Transcript This Apify actor transcribes audio or video files from publicly accessible URLs using OpenAI's Whisper API. To use this actor, you'll need to provide your own OpenAI API key. It supports multiple languages and highly customizable parameters, enabling precise control over the transcription process. The actor processes each provided URL, downloads the corresponding audio or video files, transcribes them via OpenAI, and securely stores the resulting transcripts in Apify's Storage under the Key-Value Store. --- ## 🚀 Features - Automatic language detection or manual language specification from an extensive list. - Capability to process multiple audio or video URLs simultaneously. - Versatile output formats including plain text, JSON, SRT, VTT, and verbose JSON. - Optional inclusion of timestamps for individual words (when using verbose JSON format). - Fine-tuning through parameters such as temperature, compression ratio thresholds, and speech detection thresholds. - Secure handling of your OpenAI API key, hidden from logs for added safety. --- ## 🔧 Input Configuration Configure your actor with the following parameters: | Parameter | Description | Required | |-------------------------------------|----------------------------------------------------------------------------------|----------| | url | Array of publicly accessible audio/video file URLs | ✅ | | language | Language selection or set to Auto-detect | ❌ | | temperature | Floating-point temperature to control variability in transcription | ❌ | | response_format | Desired transcript format (text, srt, vtt, json, verbose_json) | ❌ | | word_timestamps | Include timestamps per word (only valid when using verbose_json format) | ❌ | | prompt | Additional textual context to enhance transcription accuracy | ❌ | | temperature_increment_on_fallback | Increment in temperature if the initial transcription attempt fails | ❌ | | compression_ratio_threshold | Maximum allowable compression ratio for transcript acceptance | ❌ | | logprob_threshold | Minimum log probability required for transcript segments | ❌ | | no_speech_threshold | Probability threshold to detect segments with no speech | ❌ | | openai_api_key | Your personal OpenAI API key (kept secure and hidden) | ✅ | --- ## 📥 Example Input json { "url": [ { "url": "https://example.com/sample-audio.mp3" } ], "language": "Auto-detect", "temperature": "0.0", "response_format": "text", "word_timestamps": false, "prompt": "", "temperature_increment_on_fallback": 0, "compression_ratio_threshold": 2, "logprob_threshold": -1, "no_speech_threshold": 1, "openai_api_key": "YOUR_OPENAI_API_KEY" } --- ## 📤 Output Transcription results are securely stored within Apify's Storage under the Key-Value Store. Each transcript is saved individually with an identifiable key for convenient access.
