Hi,

I want to convert text to audio with time up to 50 seconds. Is there any way to calculate the time before converting? If possible, could the number of characters in relation to speech rate be calculated?

Thanks.

    Hello,

    Based on my understanding, I don't see one in Speech to Text service. I will check this again with product group to see if there any roadmap regarding to this.

    One way you can estimate is the average word length is 4.7 characters. Make it up to 5 to give some room for error. the Average person speaks 150 words per minute. So you use about 750 characters per minute of speech. You can figure out the rest of the estimations yourself.

    Regards,
    Yutong
