ai-pronunciation-trainer

What it does

Read the shown sentence aloud and it evaluates your pronunciation — aimed at the gap where you can't judge your own accent and can't ask a native speaker every time. There's a hosted version that needs nothing installed, best on desktop Chrome and slow on the first request while it warms up; audio goes to the author's service. You can type your own text before evaluating. Scores are a rough signal, not a verdict on being understood. Quiet since August 2025. AGPL-3.0.
