User reviews

This is really good

Works pretty well, few bugs with voice generation where if you press the play button as it’s generating it will just not work anymore so you have to leave the project and reopen it, but otherwise pretty awesome. Oh, also, it was very generous to offer paid features only by watching ads and getting them forever. It’s just tedious, but I suppose it’s the price I have to pay to be able to use things.

便利だが、使いにくい。

VOICEVOXの他に、UTAU音源が使えるということでインストールしました。

ミッションをこなしていけば、使える機能も増え、ボイスバンクを追加するためのポイントも少なくなる仕様なのはいいと思います。ただし、今後のために以下の点を改善点としてあげます。

・一度ファイルに名前を付けると後から変えられない。

・UTAU音源の中のフォルダ名が同じだと勝手に歌い手が統合されてしまう。

・音声を再生している途中で画面が何度も固まる。

・歌詞を入力しても一部の音声がドレミでしか歌わない。

今後のアップデートで改善して頂けると助かります。

很好用,新手推荐

很好用呀,俊达萌有好多声线,满足了我们的需求,还可以导入声库,新手也能马上就熟练

优秀

算是一个比较廉价的搞术力口的方式了,但是我目前没玩明白怎么去微操每一个音符的音量大小,还有就是得看点广告,这个问题不大。目前里面有免费自带的声库。

大好きなのです!

MIDIファイルも読み込めるし、広告さえ見れば好きなモデルを読み込めるのです。UTAUがスマホでできるのはすごくいいので、愛用しているのです。だけど電池の減りが早いし、すぐ本体があつ〜くなるのです。まあしょうがないとは思うのです。あと、無料だとピッチの編集ができないのです。それが辛いのです🥲‎なんか条件付きでもいいので、無料で少しでもできるようになってくれると嬉しいのです!
