| # Documentation Dataset: TTS_Multilingual_Data | |
| ## Dataset Summary | |
| This large-scale multilingual corpus is designed for linguistic analysis and the development of speech processing models. It supports tasks such as **Text-to-Speech (TTS)**, **Automatic Speech Recognition (ASR)**, and **speaker identification**. Structured in **Parquet format**, it serves as a key resource for training and evaluating models, using metrics tailored to ASR and speech technologies. | |
| ## Thematic Categories | |
| Our dataset is organized into the following thematic categories. Please note that all audio files have a maximum duration of **20 seconds**. | |
| ### Speeches & Conferences | |
| - "TED talk" | |
| - "political speech" | |
| - "interview" | |
| - "podcast" | |
| ### Conversations & Dialogues | |
| - "phone conversation" | |
| - "spontaneous dialogue" | |
| - "group discussion" | |
| - "audio interview" | |
| ### Media Content & Entertainment | |
| - "radio clip" | |
| - "radio commentary" | |
| - "audio narration" | |
| ### Instructions & Voice Assistants | |
| - "voice commands" | |
| - "voice assistant" | |
| - "audio notification" | |
| - "automated message" | |
| ### Informal Language & Common Expressions | |
| - "slang" | |
| - "French expressions" | |
| - "colloquial language" | |
| - "youth speech" | |
| - "emotions in speech" | |
| ### Accessibility & Inclusion | |
| - "speech with an accent" | |
| - "elderly voices" | |
| - "children speaking" | |
| ### Literature & Culture | |
| - "literature" | |
| - "tale" | |
| - "fable" | |
| - "poetry" | |
| - "novel excerpt" | |
| ## Supported Tasks | |
| - **Text-to-Speech (TTS)**: The dataset can be used to train models for generating speech from text. | |
| - **Automatic Speech Recognition (ASR)**: The dataset can be used to train models for transcribing speech to text. The most common evaluation metric is the **Word Error Rate (WER)**. | |
| - **Speaker Identification**: The dataset supports tasks related to identifying speakers based on their voice. | |
| ## Dataset Structure | |
| ### Organisation of the Project | |
| The dataset, **TTS_Multilingual_Data**, is organized as follows: | |
| containing one subfolder. The train subfolder includes data files in Parquet format (e.g., data1.parquet), while the audio subfolder contains audio files in WAV format (e.g., audio1.wav). Additionally, a readme.md file at the root level provides detailed information about the dataset's content and usage. | |
| ### Columns | |
| - **audio_path** (string): Path to the audio file. | |
| - **text** (string): Ground truth transcription. | |
| - **duration** (float64): Duration of the audio file in seconds. | |
| - **speaker_id** (string or int): Identifier for the speaker. | |
| - **audio_format** (string): Format of the audio file (e.g., WAV, MP3). | |
| - **sampling_rate** (int): Sampling rate of the audio file. | |
| - **language** (string): Language of the transcription. | |
| - **gender** (string): Gender of the speaker (if available). | |
| ## File Format | |
| The dataset is delivered in **Parquet format**, optimized for efficient storage and processing. | |
