Budget: 1500 EUR Deadline: 2 days
The best solution will be:
+ transcription of the speaker using AI API (Gemini, for example, or Wisper);
+ voiceover from ElevenLabs (you can choose the voice you like);
+ removal of the previous speaker and overlaying new voiceover - any editing program, I use CapCut.
I have done similar work more than once, and I have done transcription for dozens and hundreds of hours, so you can reach out.
The cost per minute is 6 euros, part of which will go to pay for the AI and part to the platform's commission. Therefore, I set the total cost at around that, we can discuss in more detail in private messages.
