ResponsiveVoice has three tiers. The Free plan costs $0 and is available for non-commercial personal or non-profit projects — it requires a visible attribution link to responsivevoice.org and usage limits may be applied. The Pro plan (most popular) costs $39 per month billed annually (2 months free, equivalent to $468/year) or $49 per month billed monthly ($588/year). Pro unlocks commercial use, unlimited usage, advanced engagement features, full accessibility tools, SDK access, and source editing with no attribution required. Enterprise pricing is custom and includes volume discounts, priority support, and multiple seats — contact sales for a quote.
Yes, but only for non-commercial use. The Free plan provides all 51 language voices, the API, WordPress plugin, voice message editor, page welcome message, select-text-to-speak-it, and speaking menus and links. The key restrictions are: you must add a visible attribution link to responsivevoice.org in a prominent place (such as the site footer), usage limits may be applied, and the Free plan cannot be used for commercial purposes. For any commercial website, app, or product, you need the Pro plan at $39 per month (billed annually) or $49 per month (billed monthly).
Integration requires just one line of JavaScript. You register at responsivevoice.org, receive a unique API key, then add the ResponsiveVoice script tag to your HTML referencing code.responsivevoice.org with your key. To make your site speak, call responsiveVoice.speak('Hello World') from anywhere in your JavaScript. For WordPress, a plugin provides shortcodes like [responsivevoice_button] to add listen buttons without coding. The SDK offers pre-built components for play buttons, text selection reading, spoken navigation, background audio, and animated speaking avatars.
ResponsiveVoice supports 51 languages and voices, available on both the Free and Pro plans. The library leverages native HTML5 speech synthesis voices built into the user's browser, with the Google Speech API as a fallback on devices that lack native support. An important caveat: voice availability depends on the end user's browser and device — ResponsiveVoice cannot guarantee that all voices will be available on all platforms. If a voice becomes unavailable on a platform, it is removed from the supported list. Automatic language detection is available via the SDK.
No. ResponsiveVoice generates speech in real time directly in the browser — it does not produce MP3, WAV, or any downloadable audio files. The speech output plays through the browser's audio system and is not recorded or saved. If you need to generate downloadable audio files for podcasts, voiceovers, or offline content, you should consider alternatives like ElevenLabs, Amazon Polly, or Google Cloud Text-to-Speech that provide audio file generation APIs.
Yes. ResponsiveVoice provides a WordPress plugin that works with shortcodes for easy integration without writing JavaScript. Use `[responsivevoice_button voice="UK English Female" buttontext="Listen to Post"]` to add a TTS button to any page or post, or wrap text in `[responsivevoice]...[/responsivevoice]` tags to create buttons that read only specific content. The plugin is available on both the Free plan (with attribution link required and non-commercial use only) and Pro plan ($39 per month billed annually or $49 monthly) for commercial use with unlimited usage.
ResponsiveVoice includes several web accessibility features. The Free plan offers select-text-to-speak-it (users highlight text and hear it read aloud) and speaking menus and links (navigation elements spoken on hover or focus). The Pro plan ($39 per month billed annually) adds spoken tab navigation (screen reader-like keyboard navigation where page elements are announced as users tab through them) and spoken paragraph navigation. These features help websites improve accessibility compliance by providing audio alternatives to visual content for users with visual impairments or reading difficulties.
ResponsiveVoice serves a fundamentally different use case. It is a lightweight JavaScript library designed for adding real-time, browser-based TTS to websites — it generates speech on the client side using the browser's native voices or Google Speech API, requires minimal integration (one line of code), and costs $39 per month (Pro annual) for commercial use. ElevenLabs and Amazon Polly are cloud-based neural TTS services that generate high-fidelity audio files via API calls, support custom voice cloning, and are priced per character or per request. Choose ResponsiveVoice when you need simple website voice features with fast setup; choose ElevenLabs or Polly when you need premium voice quality, audio file generation, or custom voices.
