Response
Language detection completed successfully.
Human-readable language name (e.g. "English", "French", "Mandarin"). Suitable for display to end users.
"English"
Lowercase ISO 639-1 language code (e.g. "en", "fr", "zh"). Suitable for routing, locale switching, or BCP-47 tags.
"en"
Probability associated with the predicted language, in the range 0.0-1.0. Higher means more confident.
0 <= x <= 10.9847
Total duration of the decoded audio in milliseconds. Note: only the first 30 seconds are analyzed regardless of this value.
x >= 014253
