Convert your text into speech and listen to it
Type the text you want to convert in the text area. You can also click the sample buttons to quickly load example texts.
Select your preferred voice, speed, pitch, and volume. Move each slider to find the optimal settings for your needs.
Click the play button to start speech synthesis. Use pause, resume, and stop buttons to control playback as needed.
Text-to-Speech (TTS) is a technology that converts written text into natural-sounding spoken voice. This technology uses artificial intelligence and speech synthesis algorithms to read text aloud, and is widely used in various fields such as accessibility tools for visually impaired people, language learning, audiobook production, and navigation systems. Recent advances in deep learning have enabled the generation of more natural and human-like voices. Modern TTS systems can even mimic emotions and speaking styles, making them increasingly versatile for content creation and communication applications.
This tool uses the Web Speech API, so it works on most modern browsers including Chrome, Microsoft Edge, Safari, and Opera. Firefox has limited support. Each browser uses different speech engines, so voice quality and available voices may vary. Chrome uses Google TTS, Safari uses Apple's Siri voices, and Edge uses Microsoft's Azure voices. For the best experience, we recommend using the latest version of Chrome or Edge browser. Mobile browsers also support TTS, but functionality may be limited compared to desktop versions.
Speed can be adjusted from 0.5x to 2.0x, with 1.0x being the default. Slower speeds are useful for language learning or checking pronunciation accuracy, while faster speeds are great for quickly consuming long texts. Pitch ranges from 0.5 to 2.0, with 1.0 as the default. Lower pitch creates a deeper, lower voice, while higher pitch produces a brighter, higher voice. Adjust each slider to find the settings that sound best to you. Note that changes are not applied in real-time, so you need to replay after making adjustments.
Yes, clicking the pause button while speech is playing will stop playback at the current position. Clicking the resume button will restart playback from where it was paused. The stop button completely terminates playback and requires starting over from the beginning. This feature is useful when listening to long texts and needing to take a break. However, the pause functionality may not work properly in some browsers, in which case you should use the stop and replay method instead.
Default browser TTS engines are optimized for English, so Korean voice may sound somewhat unnatural. The quality of Korean voice varies depending on your operating system, browser, and installed voice packs. On Windows, you can install additional Korean voice packs for more natural speech. macOS and iOS use Siri's Korean voice, providing relatively natural results. Chrome on Android uses Google TTS with Korean support. If you need higher quality Korean TTS, consider professional services like Naver Clova, Google Cloud TTS, or AWS Polly.
The Web Speech API generally supports up to about 32,000 characters, but actual limits vary by browser and speech engine. Very long texts may cause memory issues or playback interruptions, so if you need to read lengthy documents, it's better to split them into sections. Most reliably, the tool works with texts under 5,000 characters. Texts with many special characters or emojis may produce unexpected pronunciations. Also, some browsers may require network connection, so functionality may be limited in offline environments. For optimal performance, keep texts concise and well-formatted.
