A SpVoice object usually referred to simply as a voice, is created with default property settings so that it is ready to speak immediately. An application can create numerous SpVoice objects, each independent of and capable of interacting with the others. The SpVoice object brings the text-to-speech (TTS) engine capabilities to applications using SAPI automation. We will just only call the Speech API namespace for this program and with the use of Spvoice object. This is my another tutorial in VB.NET that converts an inputted text into a speech or voice.
