Backgrounds: As Chinese who work for cross-border e-commerce companies, we do business with global customers. so multilanguage is an advantage skill. Even though most of us have learned these foreign languages in school, like English, French, German, Spanish, etc., when it comes to formal business negotiation scenarios, our speak is not as fluent as the way we talk in our first language, which is Chinese. We know what we should talk about in our minds, but we can't speak fluently or smartly in real time. Besides, we will lose our confidence because we think the way we talk is stupid. So we need to Practice, cause Practice makes Perfect. But most of us have no native-speaker friends who can help us practice and optimize our pronunciation and communication expression ways to make it sound more clear and professional. Also, the one-to-one private speaking tutor is too expensive. Solutions: I am the one who has been through the above process and has these pain points. Since we are not developers, I came up with an AI audio solution to solve this problem. Which is, combining the custom GPT in ChatGPT Store with the ElevenLabs Reader APP. This custom GPT aims to help users tutor their speaking skills in business scenarios through role play. Starts by letting the user choose a specific language they want to use for practice, then asking them which business topic they want to practice, and then guiding the user to use the voice feature in their ChatGPT app to start the conversation. After the conversation, the GPT will generate all of the feedback as a text file, and users can import this file or directly just paste this conversation feedback to the ElevenLabs Reader App, then they can choose different voices and tones to further practice with.
