Overview of Boyomi
Boyomi is an advanced yet lightweight text-to-speech (TTS) app developed by Nekomimimi, designed to make digital communication more dynamic and inclusive. Whether you want to convert written text into spoken words for accessibility purposes, create narrations for videos, or simply hear your own text read aloud, Boyomi offers an intuitive and customizable experience that adapts to your needs.
Launched on October 12, 2025, under the package name jp.nekomimimi.boyomi, this free Android app supports Android 5.0 or higher and includes full English compatibility. It leverages the AquesTalk speech synthesis engine, a highly regarded library developed by AQUEST Co., Ltd., to ensure clear, smooth, and consistent voice output.
With features like 19 voice types, adjustable speech speed and pitch, and the ability to save outputs as audio (WAV) or video (MP4) files, Boyomi delivers a powerful and flexible voice synthesis experience that’s perfect for both personal and professional use.
Why Boyomi Stands Out
1. Seamless Text-to-Speech Conversion
At its core, Boyomi transforms any piece of text into realistic speech with remarkable accuracy. Whether reading books, generating narration, or supporting communication, the app provides a dependable voice output that enhances how users interact with text.
2. Designed for Accessibility and Versatility
Boyomi is especially valuable for users who face challenges in verbal communication or prefer to listen rather than read. It also serves creators and educators looking for a tool to produce high-quality audio or video narrations easily.
3. Simple Yet Powerful Interface
The app’s minimalistic design ensures a user-friendly experience. Input your text, adjust settings, and generate speech with just a few taps—making Boyomi suitable for users of all technical backgrounds.
Customizable Text-to-Speech Features
1. Multiple Voice Types
Boyomi includes 19 distinct voice options, ranging from standard human-like tones to more robotic or stylized ones. This variety allows users to pick the perfect voice for their intended purpose—be it professional presentations, character voices, or accessibility support.
2. Adjustable Speech Parameters
To create a personalized listening experience, Boyomi offers full control over the following parameters:
- Speed: Fine-tune how fast or slow the text is spoken.
- Pitch: Adjust the tonal height of the voice to sound deeper or higher.
- Intonation: Control the rise and fall of the voice for more natural or monotone delivery.
For users who prefer a flat or mechanical style, Boyomi also features a monotone mode, removing all intonation for consistent tone delivery.
3. Real-Time Preview
Instantly preview your audio adjustments before saving or exporting, ensuring the final output sounds exactly how you envision it.
4. Language Support
While optimized for English, Boyomi supports other languages depending on your device’s locale, making it adaptable for multilingual environments.
Audio and File-Sharing Capabilities
1. Export Audio and Video
Once your text is converted, Boyomi allows you to save your work in two major formats:
- WAV (Audio): Ideal for podcasts, accessibility aids, or voice memos.
- MP4 (Video): Great for sharing on social platforms, integrating into video projects, or using as voiceover content.
2. Automatic File Organization
On devices running Android 11 or higher, all exported files are neatly stored in dedicated folders such as /Boyomi under standard media categories. This makes locating and managing your creations effortless.
For users on older Android versions, Boyomi ensures that all files remain accessible through simple file path organization.
3. Easy Sharing Options
You can share generated files directly through messaging apps, cloud storage, or social media. Whether for collaborative projects or personal enjoyment, Boyomi ensures fast and seamless file distribution.
Lightweight and Efficient Voice Synthesis App
1. Powered by AquesTalk Technology
Boyomi is built using the AquesTalk voice synthesis engine from AQUEST Co., Ltd., renowned for its clarity, efficiency, and low memory consumption. This technology ensures lifelike audio quality without taxing your device’s performance.
2. Optimized for Speed and Stability
The app processes speech quickly without freezing or lagging, even on mid-range Android devices. Its compact design ensures smooth operation while keeping storage and battery usage minimal.
3. Privacy-Conscious Design
While Boyomi requests certain permissions such as network access (for saving video files or displaying ads), it does so only when necessary. The app prioritizes user privacy, storing files locally unless manually shared by the user.
