How it works
Audio files are automatically transcribed to text using speech recognition, then the transcript is analyzed by all enabled text-based policies. This means any policy that works on text (toxicity, hate, PII, wordlists, guidelines, etc.) also works on audio with zero additional configuration.
const result = await moderationApi.content.submit({
content: {
type: "audio",
