## What it is
Praat is a desktop application for analyzing, synthesizing, and manipulating speech, widely used in phonetics research and teaching. It provides spectrograms, pitch/formant/intensity analysis, speech labeling with IPA, text-to-speech, and statistical and neural learning tools.

## Use cases
- analyze pitch and formants in speech recordings
- generate spectrograms of audio files
- annotate and segment speech with IPA labels
- synthesize speech from pitch and formant curves
- manipulate pitch and duration of speech utterances
- run listening experiments for phonetics research
- measure voice quality jitter and shimmer

## When to choose
- you need a free, mature tool for phonetic speech analysis
- you want publication-quality acoustic figures like spectrograms
- you need manual speech annotation with multi-tier labeling
- you teach or research linguistics and phonetics

## When to avoid
- you need programmatic speech processing in a Python/ML pipeline rather than a GUI
- you need real-time or streaming audio analysis
- you want a modern collaborative or web-based tool
