What FlowSpeech Sound Effects is
FlowSpeech Sound Effects is a web generator that creates sound effects from text prompts and can also add effects to video. Prompts can describe intensity, distance, texture and emotion, while a precise duration control supports cuts, loops and transitions. The standard output shown is MP3 at 44.1 kHz and 128 kbps, and each generation uses 2,500 credits. Sound descriptions can contain up to 450 characters. FlowSpeech describes uses in video, audiobooks, podcasts, games and ads, and says generated effects may be used in YouTube videos, podcasts, ads and apps. Free access provides 2,000 credits monthly for guests or 10,000 for signed-in users. Paid monthly plans are Basic at 19.00 USD, Pro at 59.00 USD and Scale at 189.00 USD, with increasing credit allowances and Gemini TTS API access using shared credits. FlowSpeech says it does not store user data, but authorized content goes to a third-party AI platform and private information should not be entered.
