GARAGEM: General Automotive Real and Artificial speech corpus for Garage Environments and Maintenance in brazilian portuguese

General Description This dataset is a collection of audio recordings focused on the automotive workshop domain, consisting of a real dataset extracted from YouTube and two synthetic datasets generated by different text-to-speech APIs. The total dataset contains approximately 34 hours of audio. Dataset Structure The dataset is organized into three main subsets: 1. YouTube Dataset (Real) Contains 4,412 audio segments (9 hours and 45 minutes) extracted from YouTube channels focused on automotive workshop topics. Split:- Training: 3,121 segments (6 hours and 51 minutes)- Test: 1,291 segments (2 hours and 54 minutes) Metadata Files:- train_metadata_youtube.csv- test_metadata_youtube.csv Metadata columns:- url: YouTube video URL- start_timestamp: Segment start time- end_timestamp: Segment end time- human_transcription: Human-annotated transcription 2. Google Cloud Dataset (Synthetic) Contains 6,367 synthetic audio segments (11 hours and 15 minutes) generated by Google Cloud API. Format: WAV, 16 KHz Metadata File:- metadata_google_cloud.csv Metadata columns:- audio_filename: Audio file- transcription: Transcription used to generate the audio- speaker: Speaker voice defined in generation configuration 3. Gemini Dataset (Synthetic) Contains 6,367 synthetic audio segments (12 hours and 49 minutes) generated by Google API with Gemini assistance. Format: WAV, 16 KHz Metadata File:- metadata_gemini.csv Metadata columns:- audio_filename: Audio file- transcription: Transcription used to generate the audio- speaker: Speaker voice defined in generation configuration Automotive Domain Dictionary The dataset includes a dictionary file (`dictionary.csv`) containing automotive workshop terminology used for generating synthetic sentences. File: dictionary.csv Columns:- term: Automotive workshop term- meaning: Definition of the term (when necessary to assist in generation)- source: Term category Term Distribution:- Automotive parts: 330 terms- Generic term: 142 terms- Car model: 136 terms- Automotive brands: 113 terms Total terms: 721 This dictionary was used as the basis for generating the synthetic sentences present in the dataset, ensuring domain-specific vocabulary coverage.
