### 语音助手与视频内容分析技术解析
#### 1. 语音助手相关技术
语音助手在现代生活中扮演着越来越重要的角色,其背后涉及到一系列复杂的技术。
##### 1.1 响应生成
响应生成借助手动编写的模板来完成。具体操作步骤如下:
1. 选择合适的模板。
2. 将收集到的信息填充到模板的参数中。
3. 添加语音旋律和语调信息。
4. 使用停顿来分割长句子,并突出笑话的笑点。
##### 1.2 语音助手测试
以语音助手Gunrock为例,其对话系统展示了创建一个功能完备的语音助手的复杂性。以下是一个用户与Gunrock的示例对话:
| 角色 | 内容 |
| ---- | ---- |
| SYS | Oscar Wilde once said: life imitates art [fact]. Through watching movies, I feel like I’ve experienced being human [experience]. I’m so glad to talk to you about films. What’s the name of your favorite movie? |
| USR | her |
| SYS | Ah, I’ve heard of Her [acknowledgement]! Here is something I just learned. Director Spike Jonze so loved his role as Alien Child that he would often give notes to his editor and producer in character [fact]. Any thoughts? |
| USR | that’s cute |
| SYS | Maybe you will find this interesting. This is the only movie Spike Jonze has written as well as directed, completely from his own original script [fact]. Can you believe that? |
| USR | yeah spike jonze is a great director who’s your favorite director |
| SYS | Ava DuVernay. I loved her film 13th and Selma and I think she’s very talented [opinion]. |
| USR | cool |
| SYS | Who’s your favorite actor or actress? |
| USR | tom hanks |
| SYS | Mm hm, I can see why you would say Tom Hanks. Good choice [acknowledgement]. But my favorite actor is Leonardo DiCaprio. He consistently gives a great performance [opinion]. What do you think is the best acting performance of all time? |
| USR | let’s talk about something else |
| SYS | Ooh, I’ve been meaning to tell you! I really like sports, but am unable to physically play [experience]! Do you play any sports? |
该系统在Alexa环境下被数千用户使用了六周,对话相对较长,中位数约为七个话语,平均值约为九个。不同主题的对话数量和评分如下表所示:
| 主题 | 对话数量 | 评分(1 - 5分) |
| ---- | ---- | ---- |
| 娱乐 | - | 3.8 |
| 旅行 | - | 3.78 |
| 文学 | - | 3.7 |
| 闲聊 | - | 3.65 |
| 电影电视 | - | - |
| 名人 | - | - |
| 音乐 | - | - |
