计算机技术已经发展到这样的程度：音频分析技术以前是语音科学和工程研究实验室的神圣领域，现在任何在家庭或办公室使用现代 PC 机的人都可以使用。大部分分析可以实时进行。因此，目前在歌唱课程中提供实时视觉反馈是完全可行的，并且现在有许多系统可供使用。有大量（完善的）文献描述了在可以提供视觉反馈的环境中训练歌声时发生的可量化的变化。本文讨论了声音的产生和那些可以使用当今的多媒体 PC 机进行量化的元素、实时视觉反馈在歌唱课程中的使用以及了解此类系统中使用的典型分析算法背后的原理的重要性。结果表明，实时显示在歌唱课中很有用。显示应该清晰明确，用户必须了解对它们的期望。应谨慎更改用户控制的参数，并对输出的外观以及可能发生的任何错误的影响有充分的了解。
Computer technology has advanced to the point where audio analysis techniques, previously the hallowed preserve of speech science and engineering research laboratories, are now available to anyone who makes use of a modern PC machine in the home or office. Much of this analysis can be carried out in real-time. Thus it is currently perfectly feasible to make available real-time visual feedback in singing lessons, and a number of systems are now available. There is a considerable body of (well-established) literature describing quantifiable changes that occur when the singing voice is trained in a context within which visual feedback can be offered. This paper discusses voice production and those elements that can be quantified using today's multimedia PC machines, the use of real-time visual feedback in singing lessons and the importance of some understanding of the principles behind typical analysis algorithms employed in such systems. It is shown that real-time displays are useful in singing lessons. Displays should be clear and unambiguous and users must be aware of what is expected of them. User-controlled parameters should be altered with caution with an informed expectation of what the output might look like and the impact of any errors that are likely to occur.
