操作方式	优点	缺点
长按语音键开启	可以清晰地判断语音输入的结束状态	操作复杂，易误操作，物理按键容易损坏
按键即可开启	操作相对方便
纯语音方式开启	操作的自由度和连贯性较高	语音识别技术要求较高，易受外界环境影响

页面显示方式	优点	缺点
全屏显示	可使用户聚焦到语音模式下	页面跳转过大，操作不流畅
覆盖屏幕中间显示	页面跳转不大，操作流畅	当前页面的部分信息容易被覆盖，播放时易覆盖主题信息
覆盖屏幕上方显示		当前页面的部分信息容易被覆盖，首页时易覆盖导航信息
覆盖屏幕下方显示		当前页面的部分信息容易被覆盖，播放时易覆盖字幕等信息

动画形象显示与否	优点	缺点
显示	对于品牌推广有辅助作用	卡通形象无特色，页面显示相对繁杂
不显示	界面简洁，用户更容易聚焦搜索本身；没有明确的卡通形象，使用户有一定的想象空间	语音对话时场景的真实度可能会有所欠缺

操作反馈方式	优点	缺点
直接执行	搜索的流程快速简单流畅	容易出现识别错误情况
等待数秒后自动执行	给予用户修改的机会，减少错误几率	等待时间变长
确认识别结果后执行	避免出现错误	操作步骤增加，搜索时间变长

语音搜索结果显示方式	优点	缺点
覆盖显示	保证当前页面不被打断	界面显示比较乱
