Work with the talk you already recorded.
A lecture, interview, or spoken presentation may be difficult to record again. Upload the existing audio and test whether speech restoration makes it easier to follow.
Listen for clarity, not just less room sound.
Compare a passage with clear pauses and a passage with continuous speech. Pay attention to how the words and the voice sound in each version. Heavy reverberation and other damage can limit the result.
