+         - **Note** that bark can only generate 14 seconds of audio, so if you want to generate a longer audio, you have to use  "[split]" in your text.  
+         - For example, if you want to generate a 30 seconds audio, you have to write your text like this :
+           - "This is the first part of my text **[split]** This is the second part of my text"

       7. Silence : Time in seconds between each punctuation(。！!.？?,). Default is 0.25 seconds.
       8. See Bark [documentation](https://github.com/suno-ai/bark/) for more details.
