To test maternal voice alarm effectiveness under residential conditions and determine whether personalizing the maternal voice alarm message with the child's first name improves effectiveness.
Using a randomized, nonblinded, repeated measures design, we compared 3 maternal voice smoke alarms with respect to their ability to awaken 176 children 5-12 years old from stage 4 slow-wave sleep and prompt their performance of an escape procedure. A conventional residential high-frequency tone smoke alarm was used as a comparative reference. Children's sleep stage was monitored in a residence-like research setting.
Maternal voice alarms awakened 86%-91% of children and prompted 84%-86% to escape compared with 53% awakened and 51% escaped for the tone alarm. A sleeping child was 2.9-3.4 times more likely to be awakened by each of the 3 voice alarms than the tone alarm. The median time to awaken was 156 seconds for the tone alarm and 2 seconds for each voice alarm. The proportions of children who awakened and escaped differed significantly between the tone alarm and each voice alarm, but no significant differences were found between each pair of the voice alarms, regardless of whether the child's first name was included in the alarm message.
The maternal voice alarms significantly outperformed the tone alarm under residential conditions. Personalizing the alarm message with the child's first name did not increase alarm effectiveness. These findings have important implications for development of an effective and practical smoke alarm for children.

测试家庭环境下母亲声音警报的有效性，并确定通过孩子的名字个性化母亲声音警报信息是否能提高其有效性。
我们采用随机、非盲、重复测量设计，比较了 3 种母亲声音烟雾报警器在唤醒 176 名 5-12 岁处于慢波睡眠 4 期的儿童，并促使他们执行逃生程序方面的能力。使用传统的住宅高频调谐烟雾报警器作为比较参考。在类似于居住的研究环境中监测儿童的睡眠阶段。
与调谐警报相比，母亲声音警报唤醒了 86%-91%的儿童，并促使 84%-86%的儿童逃生，而调谐警报唤醒了 53%的儿童，逃生了 51%。与调谐警报相比，每个声音警报唤醒熟睡儿童的可能性要高出 2.9-3.4 倍。调谐警报唤醒的中位数时间为 156 秒，而每个声音警报的唤醒时间为 2 秒。调谐警报和每个声音警报之间，儿童醒来和逃生的比例差异显著，但无论警报信息中是否包含孩子的名字，声音警报之间都没有发现显著差异。
在家庭环境下，母亲声音警报明显优于调谐警报。通过孩子的名字个性化警报信息并未提高警报的有效性。这些发现对开发有效的实用儿童烟雾报警器具有重要意义。
