Text to Speech

You are editing a three-minute tutorial video and need to turn a 500-character set of instructions into a natural voiceover. Open this tool, paste your script, choose “Professional Female Voice,” and click “Generate.” In under 30 seconds, you can download a clear MP3 voiceover. Text-to-speech (TTS) technology converts virtually any text into speech that sounds close to a real human voice—no recording equipment or voice actor required. This tool includes a range of natural voices, from standard male and warm female voices to lively childlike voices, covering most everyday voiceover needs.

What Is Text-to-Speech?

Text-to-speech, also known as speech synthesis, uses deep-learning models to convert written text into spoken audio. The technology dates back to rule-based synthesizers from the mid-20th century, but neural vocoders such as WaveNet and Tacotron have made synthetic speech far more natural in recent years. Simply enter your text, choose a voice, and the tool analyzes intonation, pauses, and emphasis to create smooth audio.

Our tool simplifies the process into three areas: a text editor on the left, voice controls in the center, and preview and download options on the right. You do not need technical knowledge to use it—it is as straightforward as creating a voice memo.

How to Use It

When you open the tool, you will see the following layout:

1. Enter your text: Paste or type the content you want to convert in the text box at the top left. Chinese, English, and common punctuation are supported, with a maximum of 5,000 characters per generation.
2. Choose a voice: Select a voice from the “Voice Type” menu, such as “Standard Male,” “Warm Female,” “Steady Narrator,” or “Lively Child.” Each voice includes a “Play Sample” button so you can hear a short example.
3. Adjust settings: Use the sliders to set speaking rate (0.5x–2.0x), volume (0–100%), and pitch (-20 to +20). The default 1.0x rate usually sounds most natural. For short-form video narration, 1.2x–1.3x can work well.
4. Preview the result: Click “Preview” to generate and play the first 50 characters. Adjust the settings as often as needed until you are happy with the result.
5. Generate and download: Click “Generate Full Audio.” After a few seconds, a player and “Download MP3” button will appear on the right. Click it to save the file locally.

Worked Example: Creating a Product Video Voiceover

Suppose you are making a 15-second product video for Bluetooth earbuds sold on an ecommerce platform. Your script reads:

“These Bluetooth earbuds feature next-generation noise cancellation, up to 30 hours of battery life, and a comfortable, barely-there fit. Order today to save 20%, with free express delivery.”

The script is about 70 characters in Chinese. Here is how to turn it into a voiceover:

1. Paste the script into the text box.
2. Select “Enthusiastic Male Voice” under Voice Type for a promotional tone.
3. Set the speaking rate to 1.1x for a slightly faster, more urgent delivery; keep volume at 100%; and set pitch to 0 for a neutral tone.
4. Click “Preview” to hear the synthesized result. The pacing should be clear and engaging.
5. Once everything sounds right, click “Generate Full Audio” and download the MP3 file.

Drag the downloaded MP3 into CapCut, Premiere, or another video editor, place it on the audio track, and align it with your visuals. You will have a polished voiceover without recording anything yourself.

More Examples: Voice Settings for Different Use Cases

Here are two more examples showing how voice and setting changes affect the final result.

Example 1: Online course narration
For a 300-character explanation of a math concept, you need a calm, clear delivery. Choose “Steady Female Voice,” set the rate to 0.9x so learners can follow along, volume to 90%, and pitch to 0. The result sounds like a patient teacher, with natural pauses and clear emphasis.

Example 2: Funny short-form video
For a humorous script that needs fast, upbeat delivery, choose “Lively Child Voice,” set the rate to 1.3x, volume to 100%, and pitch to +5 for a more playful feel. The faster, cartoon-like result works well with lighthearted video content.

These examples show how changing only the voice and speaking rate can create completely different listening experiences. Try several voices to find the one that best matches your content.

Popular Use Cases

• Social media video creation: Short-form video creators often need narration for their visuals. Enter your script, choose a voice that suits your channel, and avoid repeated recording while keeping pronunciation and pacing consistent.
• Online course production: Teachers and trainers can convert lesson plans into narration for course materials or listening exercises. Generate audio in sections and organize files by chapter to reduce preparation time.
• Store and mall announcements: Promotional announcements need regular updates. Administrators can simply revise the script and generate new audio for their PA system, without hiring a professional announcer for every update.
• Audiobook production: For public-domain books or original writing, generating audio from long text in sections can speed up audiobook creation. It may not match human performance for emotional fiction, but it is efficient and cost-effective for non-fiction content.

Common Mistakes to Avoid

1. Ignoring punctuation: TTS relies on punctuation to determine pauses. Without periods and commas, the voice may run through the entire script without breathing room. Use clear punctuation when writing your script.
2. Including special characters: Emoji, full-width letters, or certain Unicode symbols can cause generation errors or garbled output. Check pasted text in a plain-text editor first.
3. Setting the speaking rate too high: Rates above 1.5x can be difficult to follow, especially in educational or explanatory content. For these use cases, we recommend staying at or below 1.2x.
4. Letting background music overpower the narration: When mixing audio in a video editor, low-volume narration can get buried under background music. Generate at 100% volume, then lower it during editing if needed.
5. Not comparing voices: Voices can differ significantly in pronunciation, style, and perceived breathiness. Do not settle for the default voice—preview several options before choosing one.

Notes

• Character limit: Each generation supports up to 5,000 characters. Split longer text into sections. If you have many sections, combine them in an audio editor or use our history feature to download them in batches.
• Copyright and responsible use: You own the audio generated with this tool, but it must not be used for fraud, deceptive advertising, harassment, or other illegal activity. Never use synthesized speech to impersonate another person.
• Device and network requirements: Generation speed depends on browser performance and network conditions. We recommend modern browsers such as Chrome or Edge and a stable internet connection. Uncalibrated microphones or low-spec devices do not affect generation, though preview playback may be affected by your system audio settings.
• Limits of emotional expression: Although modern neural models sound substantially more natural, synthetic speech cannot fully reproduce subtle human emotions such as a bitter laugh or anger. For film and video work requiring highly expressive acting, professional human recording is still recommended.
• Disclaimer: This tool is for learning, communication, and lawful use only. The developer is not responsible for consequences arising from illegal use by users.

FAQ

Q: Can I add background music while generating speech?
A: This tool currently generates voice-only audio and does not provide mixing features. After downloading the MP3, use software such as CapCut or Audacity to add background music and balance the volume levels.

Q: What file format is generated? Which players support it?
A: Audio is generated as an MP3 at 44.1 kHz and 128 kbps. It plays on computers, phones, and car audio systems, and works with all major video editing software.

Q: Can I use generated speech commercially?
A: Yes. Audio created with this tool can be used in commercial videos, ads, paid courses, and similar projects without additional authorization. However, if your script contains copyrighted material owned by someone else, you are responsible for obtaining permission to use that text.

Q: Is there a character limit? Will long generations fail?
A: Each generation supports up to 5,000 characters. Longer content must be split into sections. With a stable network, multiple generations in a short period should work normally, but keeping each request under 3,000 characters offers a more reliable experience.

Q: Can I change the emotion of the voice, such as happy or sad?
A: Emotion controls are not currently supported. Adjusting speaking rate and pitch can influence how the voice feels, but it will not apply a specific emotion label. For a stronger effect, use interjections and punctuation in your script.

Q: Can I upload my own audio as a voice template?
A: Voice cloning is not currently supported. The available voices are trained on general-purpose speech models and cannot imitate a specific person's voice.
