# AE29H_float32

**Audio Embeddings ~29 hours** dataset contains **precomputed audio embeddings** designed for **[Nanowakeword](https://github.com/arcosoph/nanowakeword)** framework. The embeddings are intended to be used as **general-purpose negative training data**, meaning the audio does **not contain the target wake word or phrase**.

Unlike raw audio datasets, the files in this dataset contain **low-dimensional audio embeddings** extracted from audio clips using a pre-trained [speech embedding](https://www.kaggle.com/models/google/speech-embedding) model. These embeddings can be directly used as input features when training wake-word detection models with NanoWakeWord.

The goal of this dataset is to provide **diverse background audio representations** (speech, environmental noise, music, etc.) that help wake-word models learn to avoid false activations.

# Dataset Source

The embeddings were generated from a subset of the **[ACAV100M](https://acav100m.github.io/)** dataset.

ACAV100M is a very large automatically curated audio-visual dataset created from millions of internet videos and designed for large-scale audio-visual learning. It contains diverse real-world audio such as speech, environmental sounds, music, and background noise.

For this dataset:

* A **20K subset (~2 days of audio)** from ACAV100M.
* Audio clips were processed and converted into embeddings suitable for wake-word training.
