Based on your requirements, Otter.ai would be the most suitable tool to transcribe podcast content into written text. Here are some quick steps to successfully transcribe your podcast content:

1. Sign up for a free Otter.ai account which offers 300 monthly transcription minutes and 30 minutes per conversation. If you need more time, consider the Pro plan for $10 USD per user/month.
2. Once you've signed up and logged in, navigate to the app's transcription window. Here, you can upload your audio file directly or through a link.
3. After the file has been uploaded, Otter.ai will begin to transcribe the audio. Note that accuracy varies between 75% to 90%. You can manually edit the transcription to rectify any inaccuracies. This might occur more frequently in environments with significant background noise or echo, or when the speaker has a heavy accent or is mumbling.
4. After the transcription is complete, you can export it as a text, docx, or PDF file as per your requirement.

In case you have trouble due to background noise or accents, consider using ElevenLabs to recreate the podcast voice in a more clear and accessible manner, and then run the recreated podcast audio through Otter.ai.

Please note, ElevenLabs is more of a voice creation and cloning tool, and it might not be necessary unless you are facing issues with Otter.ai's accuracy due to the aforementioned factors. For most users, Otter.ai alone should suffice.

To see the best results, use the tool in a quiet environment and ensure the speaker articulates their words clearly.
