Voiceprint Technology (IV): Engineering deployment of voiceprint recognition

4.1　 From model to product

4.1.1　 Model is not equal to product

For academia , Through training data , A group of voiceprint recognition models are trained by a specific algorithm , And verify its performance on the test data —— These jobs add up , Enough to constitute a complete research project . If there are some innovations or changes in data processing or training algorithms , And add some other methods to compare the experimental results , Then this work is enough to write a research paper with rich content , To publish in an academic conference or journal .

however , For the industry , Have a voice print recognition model with good performance , It's just the first step in the long march . It is necessary to deploy voiceprint recognition technology to practical and easy-to-use products , There are countless engineering problems to be solved , For example, the architecture of the system 、 Model release 、 Software maintenance , And the interaction between users and products , wait . This chapter will introduce some of the most common engineering problems , The basic architectures of the three deployment schemes are briefly described .

4.1.2　 Basic concepts of software engineering

Before introducing the engineering problems in voiceprint recognition , Considering that some readers of this book may not have any actual product level software development experience , The author first gives a very brief introduction to some basic concepts in software engineering . Although these concepts may have little to do with voiceprint recognition itself , But for readers who intend to enter the enterprise for actual product development in the future , These concepts are very important , It may even determine the success or failure of a project or a product .

Software engineering itself as a discipline , It covers a wide range of contents , Therefore, there are a vast number of books and tutorials on software engineering . For readers with limited time , Consider briefly reading the most famous 《 The way of programmer training ： The Pragmatic Programmer 》 A Book [106], Or read Google Voice engineers directly Fergus Henderson The author's thesis Software Engineering at Google [107].
