Adobe Enhance Speech vs SpeexDSP

Adobe Enhance Speech is a web tool for reducing noise and echo in voice recordings and dialogue from audio or video. It filters noise and artifacts, adjusts pitch and volume, and normalizes audio; downloads retain the imported file’s format. It accepts WAV, MP3, M4A, AAC, and FLAC audio, plus MP4, MOV, and M4V video, with uploads up to 1 GB. The free plan is audio-only, processes one file at a time, and has no strength adjustment. Each file is limited to 30 minutes and 500 MB, with one hour of enhancement per day. Firefly Pro adds video support, bulk uploads, strength controls, and up to four hours of daily enhancement for $19.99 a month, billed monthly; files can be up to two hours and 1 GB. Adobe says results depend on speaker audibility and background noise, and clearer pronunciation can produce better output. The tool is optimized for desktop and mobile browsers, including Chrome, Safari, Edge, and Firefox. It is language agnostic and does not generate or translate across languages.
