PS: Write To Speech

1 minute read


Use Powershell to get your computer to talk

To Resolve:

  1. So this is one of those things that you first start toying around with when you first start learning Powershell.

    $Speaker = New-Object -ComObject Sapi.SpVoice
    $null = $Speaker.Speak($Text)
  2. Use this code to remotely have another user hear what you type:

    Enter-PSSession -ComputerName AHoleUser -Credential (Get-Credential)
    Add-Type -Language CsharpVersion3 -TypeDefinition @'
    using System.Runtime.InteropServices;
    [Guid("5CDF2C82-841E-4546-9722-0CF74078229A"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
    interface IAudioEndpointVolume {
    // f(), g(), ... are unused COM method slots. Define these if you care
    int f(); int g(); int h(); int i();
    int SetMasterVolumeLevelScalar(float fLevel, System.Guid pguidEventContext);
    int j();
    int GetMasterVolumeLevelScalar(out float pfLevel);
    int k(); int l(); int m(); int n();
    int SetMute([MarshalAs(UnmanagedType.Bool)] bool bMute, System.Guid pguidEventContext);
    int GetMute(out bool pbMute);
    [Guid("D666063F-1587-4E43-81F1-B948E807363F"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
    interface IMMDevice {
    int Activate(ref System.Guid id, int clsCtx, int activationParams, out IAudioEndpointVolume aev);
    [Guid("A95664D2-9614-4F35-A746-DE8DB63617E6"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
    interface IMMDeviceEnumerator {
    int f(); // Unused
    int GetDefaultAudioEndpoint(int dataFlow, int role, out IMMDevice endpoint);
    [ComImport, Guid("BCDE0395-E52F-467C-8E3D-C4579291692E")] class MMDeviceEnumeratorComObject { }
    public class Audio {
    static IAudioEndpointVolume Vol() {
       var enumerator = new MMDeviceEnumeratorComObject() as IMMDeviceEnumerator;
       IMMDevice dev = null;
       Marshal.ThrowExceptionForHR(enumerator.GetDefaultAudioEndpoint(/*eRender*/ 0, /*eMultimedia*/ 1, out dev));
       IAudioEndpointVolume epv = null;
       var epvid = typeof(IAudioEndpointVolume).GUID;
       Marshal.ThrowExceptionForHR(dev.Activate(ref epvid, /*CLSCTX_ALL*/ 23, 0, out epv));
       return epv;
    public static float Volume {
       get {float v = -1; Marshal.ThrowExceptionForHR(Vol().GetMasterVolumeLevelScalar(out v)); return v;}
       set {Marshal.ThrowExceptionForHR(Vol().SetMasterVolumeLevelScalar(value, System.Guid.Empty));}
    public static bool Mute {
       get { bool mute; Marshal.ThrowExceptionForHR(Vol().GetMute(out mute)); return mute; }
       set { Marshal.ThrowExceptionForHR(Vol().SetMute(value, System.Guid.Empty)); }
    [Audio]::Mute = $false
    [Audio]::Volume = 1
    Add-Type -AssemblyName System.speech
    $speak = New-Object System.Speech.Synthesis.SpeechSynthesizer
    $speak.Speak('Hey everyone Im looking at porn over here, come check me out! This is why Im not productive')
  3. I tested the following code in my lab and it worked! It takes a while to run, but it does work! I wouldn’t ever do this though because it would unprofessional. Cool to learn though.

  4. This can be found in my gwMisc section.
