Strengths

English video pronunciation search with timestamps, IPA phonetics and subtitle context.

Search any word or phrase. Hear real speakers say it in authentic videos, with exact timestamps and synchronized subtitles.

Strengths

Prototyping or a tutorial? Pick the one that needs no API key.
Calling from a web page? You need CORS. Otherwise route requests through your own server or a serverless function.
Going to production? Favour HTTPS, a strong uptime record and a provider with clear rate limits and terms. Check each API's docs before you commit.
Still unsure? Both are free to try: send one request to each and compare the data you get back.

SayItVid API requires an API key; Free Dictionary API doesn't, so Free Dictionary API is quicker to try.

SayItVid API supports CORS, so front-end JavaScript can call it directly. Call the other from a server.
