我可以在bash脚本中与OSX`say`命令的输出进行交互吗? [英] Can I interact with the output of the OSX `say` command in a bash script?

问题描述

我在终端中运行以下行:

I have the following line that I run in terminal:

say "hello, this is the computer talking" --interactive

当我运行此命令时，计算机会说出引号中的单词，并在说出单词时突出显示这些单词.我想做的是获取每个口语的时间.例如:

When I run this command, the computer speaks the words in quotes and highlights the words as they are spoken. What I would like to do is get the time of each spoken word. For example:

• 00.00你好
• 01.23这个
• 01.78是
• 02.10的
• 02.70计算机
• 03.30谈话

我想知道是否有任何方法可以编写可以与该行的输出进行交互的bash脚本.

I am wondering if there is any way to write a bash script that would interact with the output of the line.

推荐答案

这是一个Zsh脚本，几乎可以完全满足您的要求.

Here is a Zsh script that almost does exactly what you want.

#!/bin/zsh
zmodload zsh/datetime
say --interactive "hello, this is the computer talking" | {
    counter=0
    while IFS= read -r -d $'\r' line; do
        (( counter++ )) || continue  # first line in the output of `say --interactive` suppresses the cursor; discard this line
        timestamp=$EPOCHREALTIME
        (( counter == 2 )) && offset=$timestamp  # set the timestamp of the actual first line at the offset
        (( timestamp -= offset ))
        printf '%05.2f %s\n' $timestamp ${${line%$'\e[m'*}#*$'\e[7m'}
    done
}

示例输出:

00.00 hello
00.26 ,
00.52 this
00.65 is
00.78 the
01.36 computer
02.04 talking

如果要将其转换为bash，则需要在诸如bc之类的外部命令中执行浮点运算，并且要获得准确的时间戳，您将需要coreutils date(timestamp=$(gdate +%s.%N)).

If you want to convert this to bash, then floating point arithmetic needs to be done in external commands like bc, and to get a precise timestamp you would need coreutils date (timestamp=$(gdate +%s.%N)).

顺便说一句，如果您不想看到逗号，则可以将其过滤掉.

By the way, if you don't want to see the comma, you can just filter it out.
