are available for long form or high frequency usage what file formats are supported we support common audio and video formats including mp3 wav m4a mp4 mov etc we recommend uploading clear audio for best results is my data safe very safe we adopt a use and delete policy audio files are only used for recognition and are automatically deleted from the server after processing we will never store or train on your data how is the recognition accuracy accuracy can reach over 98 under standard clarity it supports speaker diarization automatically distinguishes different speakers and generates srt subtitles with timestamps how do i export results you can preview and edit directly on the webpage after completion you can copy the text with one click or download it as txt or srt subtitle files is there a file length limit we currently support processing single files up to 1 hour long for longer videos we recommend uploading them in segments to ensure processing speed why does my generated audio sound like a robot using appropriate punctuation such as commas periods and exclamation marks in the text can make the generated speech more natural and expressive how can i make the generated speech more natural select an appropriate voice for different scenarios choose a mature and steady voice for formal occasions and a lively and bright voice for children s content how do i generate speech in multiple languages when generating speech in multiple languages ensure the text is written in the correct language and avoid mixing multiple languages within a single request what is emotion intensity emotion intensity controls how strongly the selected voice style is expressed low sounds more natural and restrained high fits most normal narration and very high works better for stronger emotions in short videos ads or notifications why don t some voices show emotion intensity or role play because different voices support different capabilities emotion intensity is shown only for voices that support style and role play is shown only for voices that support role options how should i choose emotion intensity start with low if you want a more natural tone high is enough for most everyday narration and standard dubbing use very high only when you want a more dramatic or expressive result what are phoneme and liaison tags they are text tags used to fine tune pronunciation a phoneme tag helps specify how a character should be pronounced while a liaison tag makes adjacent words connect more naturally in normal use just select the text first and click the corresponding button the system inserts the tag automatically so you do not need to write it by hand are ssml and pause tags supported yes the text box supports ssml and extension tags such as break time 1s for pauses and mstts ttsbreak strength none product name mstts ttsbreak for smoother phrase connection some advanced tags may depend on the selected voice so test with a short sentence first voiceindex ai
