If you're looking for a service that offers real-time synced lyrics for videos and podcasts, Musixmatch is a broad service that offers accurate lyrics and syncs them to the music. It's got an edge with real-time sync, which is particularly useful for videos and podcasts. It can also automatically transcribe podcasts and link to services like Spotify. It's a full-fledged service for publishing and distributing content, so it's good for artists, podcasters and others.
Another good option is the Better Lyrics browser extension. It's a useful addition to the YouTube Music experience, with time-synced lyrics, seek and real-time translations. It's lightweight, so it won't slow down your browser, and it's a good option for people who want to engage with lyrics.
If you're editing video or podcasting, Descript is a powerful service that can generate captions with AI, transcribe automatically and synchronize audio and video in real time. It's not a lyrics service, but its editing abilities and AI tools can help you make your content more accessible and engaging.
