SINGAPORE, July 08, 2025 (GLOBE NEWSWIRE) — buz, the voice messaging app that recently topped app store rankings across multiple countries, has released a product update today, with a spotlight on Japanese users. The update introduces the Kansai Vibes voice filter—buz’s most technically advanced filter to date—along with a suite of new features designed to enable more user creativity and social sharing.
Kansai Vibes: Innovation in Voice Filters
The Kansai Vibes voice filter brings vibrant regional Japanese dialects—like those from Kansai, a south-central region of Japan known for its expressive speech and major cities like Osaka and Kyoto—to life using a completely new speech synthesis approach.
Instead of simple voice conversion, buz now uses automatic speech recognition (ASR) to transcribe the user’s voice, a large language model (LLM) to rewrite it in the Kansai dialect, and finally text-to-speech (TTS) to generate a fresh, natural-sounding Kansai-accented voice. Each output is randomized, allowing for a variety of tones—from playful and anxious to bold or sarcastic—and featuring both male and female voices.
The Kansai Vibes launch is part of buz’s broader push to localize content for a culturally diverse audience. By capturing the nuance and personality of one of Japan’s regional dialects, buz is deepening its appeal among Japanese users and other international users who are interested in Japanese culture.
New ‘Featured’ Tab and Social Video Sharing
The app’s new update also debuts a Featured tab, where filters come to life with dynamic previews and social-ready content designed to spark creativity and encourage sharing. Users can now export voice-based creations directly to video, complete with visual effects and captions, then easily and quickly post them across social platforms.
New creative tools introduced in this release include fresh bubble styles, updated text templates, voice-to-video generation, and support for third-party video sharing—making it easier than ever to make voice moments into compelling, shareable content.
Global Momentum and User Excitement
buz continues its organic growth, gaining strong traction across many markets as users embrace its fresh take on voice-driven social interaction. The app is also showing strong signs of popularity among young users in Japan and around the world, reflecting its broad cross-cultural appeal. In Japan, buz has ranked #5 in the Apple App Store’s Social Networking category and #7 in Google Play’s.
Additionally, buz has reached the #1 spot in the Social Networking category of 12 countries on the App Store and four countries on Google Play. It has also ranked among the top 10 social networking apps in 133 countries on the App Store and 53 countries on Google Play, including the US, UK, Germany, Singapore, Malaysia, Thailand and Philippines. This strong viral growth across different markets demonstrates strong growth and momentum in diverse cultural contexts. With 4.9 stars on the App Store and 4.8 stars on Google Play, buz maintains one of the highest user satisfaction ratings in its category.
