## What it is
Coqui STT is an open-source deep learning toolkit for training and deploying speech-to-text models, built on TensorFlow with bindings for multiple programming languages. It offers pre-trained models, streaming and real-time inference, and multi-GPU training, though the project is no longer actively maintained.

## Use cases
- transcribe audio recordings to text
- build a voice-controlled app with speech recognition
- train a custom speech-to-text model on my own dataset
- run offline speech recognition on device
- stream live microphone audio to text in real time
- get multiple transcript candidates with confidence scores

## When to choose
- you need a self-contained, offline speech-to-text engine with small footprint
- you want to fine-tune or train an ASR model with multi-GPU support
- you need language bindings beyond Python for embedding STT in other apps

## When to avoid
- you want actively maintained software or up-to-date model accuracy
- you need state-of-the-art transcription quality, where Whisper-class models are better
- you rely on the online Model Zoo, which is no longer hosted
