A person's wife is undergoing oral surgery with a small chance of losing her ability to speak, and they want to prepare by using technology to reproduce her voice from keyboard or other input. They are looking for an open source 'deepfake toolkit' that can use pre-recorded samples of her speech to generate text-to-speech in her voice. The person is seeking recommendations for such tools or alternative solutions. They mention recording her speaking 'phonetic pangrams' as a fallback option.
