US English voices for websites and apps
Use a friendly ResponsiveVoice voice name such as US English Female, or select by BCP-47 language code with { lang: 'en-US' }. The browser SDK uses native speech where it fits and falls back to ResponsiveVoice server audio when a closer voice is needed.
| Voice name | Language code | How to select it |
|---|---|---|
| US English Female | en-US | Use by exact name, pattern, or language query. |
| US English Male | en-US | Use by exact name, pattern, or language query. |
One-line browser setup
Add US English speech with JavaScript

<script>
responsiveVoice.init({ apiKey: 'YOUR_API_KEY' });
responsiveVoice.speak("Add clear US English text to speech to your website or application with ResponsiveVoice.", "US English Female");
</script>For a first demo you can initialize without an API key and use the device voice. Register and verify your website domain to unlock the full voice catalog. For backend audio generation, use the REST API with your API key and secret.
