Build SRT leverages Apple’s built-in speech recognition framework to convert spoken audio into text. You can use the system’s native speech-to-text functionality to experience its transcription accuracy firsthand. To complement the limitations of the built-in recognizer, the app also supports manual import of natural language text, offering greater flexibility in subtitle creation. The app generates subtitle files in standard SRT format, but it does not produce new video files with embedded subtitles. The "Build SRT" App can efficiently extract the voice in the video and convert these sounds into subtitle SRT files. The generated subtitle SRT file is a universal subtitle file format, so that you can use the subtitle SRT file widely. Features: • It is very convenient to import videos from the system "Photos" and "Files" • Import videos at the same time and view subtitles according to the video at a glance • Efficiently and quickly extract the sound in the video and convert it into an SRT file • SRT files can be quickly shared on other devices.Support sharing, copying, spacing and forwarding on Apple system to facilitate exporting SRT files for modification and use. • SRT files are a universal subtitle file format and can be used widely.
