FlowSpeech Sound Effects
What it is
FlowSpeech Sound Effects is a web generator that creates sound effects from text prompts and can add effects to video. Prompts can describe intensity, distance, texture, and emotion, and a duration control sets exact lengths for cuts, loops, or transitions. The standard output shown is MP3 at 44.1 kHz and 128 kbps, with each generation costing 2,500 credits. The description field accepts up to 450 characters. FlowSpeech lists video, audiobooks, podcasts, games, and ads as use cases, and says generated sounds can be used in YouTube videos, podcasts, ads, and apps. A free plan provides 2,000 credits monthly for guests or 10,000 for signed-in users. Monthly paid plans are Basic at $19.00 with 200,000 credits, Pro at $59.00 with 1,000,000 credits, and Scale at $189.00 with 4,000,000 credits. Paid plans include Gemini TTS API access with shared credits. FlowSpeech says it does not store user data, sends authorized content to a third-party AI platform, and advises against entering private information.
