Install VB-Cable if you haven't already https://vb-audio.com/Cable/ This tool creates a virtual microphone on your Windows computer or Mac. Once installed you can then trigger audio to be played on this virual cable. 2. Open the Text to Mic app by Scorchsoft, and input your OpenAPI key. How to set up an API key: https://platform.openai.com/docs/quickstart/account-setup (note that this may require you to add your billing details to OpenAI's playground before a key can be generated) In short, you sign up, go to playground, add billing details, go to API keys, add one, copy it, paste into Text to Mic. WARNING: This will use your OpenAI key to generate audio via the OpenAI API, which will incur charges per use. So please make sure to carefully monitor use. OpenAI pricing: openai.com/pricing 3. Choose a voice that you prefer for the speech synthesis. 4. Select a playback device. I recommend you select one device to be your headphones, and the other the virtuall microphone installed above (Which is usually labelled "Cable Input (VB-Audio))" 3. Enter the text in the provided text area that you want to convert to speech. 4. Click 'Submit' to hear the spoken version of your text. 5. The 'Play Last Audio' button can be used to replay the last generated speech output. 6. You can change the API key at any time under the 'Settings' menu.
