Error message

检测到您未安装日语语音包，请去“设置”->“时间和语言”->“语音”->“添加语音”中安装日本语，以免影响正常使用。

What it means

In SelectBook_Click (View/ToastFish.xaml.cs:557), when the user selects a Japanese word book, the app iterates installed SpeechSynthesizer voices and checks for a voice whose Culture.IetfLanguageTag equals "ja-JP". If none is found (Flag stays false), it shows this WinForms MessageBox telling the user to install the Japanese voice via Windows Settings > Time & Language > Speech. This is not an exception but a hard dependency warning: ToastFish's Japanese push/pronunciation features rely on the OS TTS engine, which cannot speak ja-JP without the voice pack.

Solutions

1. Install the Japanese voice pack: Windows Settings > Time & Language > Speech > Add voices > 日本語 (ja-JP), then restart ToastFish.
2. Alternative path: Settings > Time & Language > Language > Add a language > 日本語 (include the Speech optional feature), then reboot.
3. Verify programmatically with PowerShell: Add-Type -AssemblyName System.Speech; (New-Object System.Speech.Synthesis.SpeechSynthesizer).GetInstalledVoices() and confirm a ja-JP voice appears.
4. If the app was running during installation, close and relaunch ToastFish so SpeechSynthesizer enumerates the newly installed voice.
5. If only silent push is needed and audio is unwanted, use a book without TTS dependency or ignore the dialog (the book selection still proceeds since Select.TABLE_NAME is set afterwards).

Example fix

// before
if(Flag == false)
    System.Windows.Forms.MessageBox.Show("检测到您未安装日语语音包...");
// after
if (Flag == false)
{
    var result = System.Windows.Forms.MessageBox.Show(
        "检测到您未安装日语语音包，是否打开系统设置安装？", "提示",
        MessageBoxButtons.YesNo, MessageBoxIcon.Information);
    if (result == DialogResult.Yes)
        Process.Start("ms-settings:menuspeech"); // or speech settings deep link
}

using (var synth = new System.Speech.Synthesis.SpeechSynthesizer())
{
    bool jaInstalled = synth.GetInstalledVoices()
        .Any(v => v.VoiceInfo.Culture.IetfLanguageTag == "ja-JP");
    if (!jaInstalled)
    {
        // prompt user to install the ja-JP voice pack before selecting a Japanese book
        System.Windows.Forms.MessageBox.Show("检测到您未安装日语语音包，请先在 设置>时间和语言>语音 中安装日本语。");
    }
}

When it happens

Trigger: User clicks a Japanese book entry (SelectBook_Click with a Japanese table name such as a Japanese word list) while the Windows speech synthesis API (System.Speech.Synthesis.SpeechSynthesizer.GetInstalledVoices) returns no voice with IetfLanguageTag == "ja-JP".

Common situations: Fresh Windows 10/11 installs (only the OS language's voice pack is installed by default); Windows N/KN editions missing media features; Chinese-language systems where ja-JP was never added in Settings; enterprise images that strip optional language features; running the app right after selecting a Japanese book without ever configuring speech.
