宽吻海豚（Tursiops truncatus）产生个别独特的发声-被称为“签名哨声”-被认为是作为一个单独的和同种识别系统，用于维持个人之间的一致接触。在水族馆进行了观察和回放实验，以研究这些哨声，声音交换的海豚。发声的时间模式进行了研究，通过分析两个连续的哨声之间的通话间隔。当第二个人发出的叫声与第一个人的叫声不同时，大多数叫声都短于1秒。然而，当两个连续的呼叫由同一个人产生时，第二个呼叫很少在第一个呼叫的1秒内发生。这些结果表明，第二个哨子可能是由不同的呼叫者在响应第一个哨子;然而，在没有响应的情况下，第一个呼叫者很可能会给进一步的哨子。声学分析的结果表明，在这项研究中使用的海豚大多数使用的签名哨声在记录的声音交流。
Bottlenose dolphins (Tursiops truncatus) produce individually distinctive vocalizations—referred to as “signature whistles”—that are thought to function as an individual and conspecific recognition system for maintenance of consistent contact between individuals. Observations and playback experiments were conducted at aquariums to study these whistle–vocal exchanges in bottlenose dolphins. Temporal patterns of vocalization were examined by analyzing the intercall intervals between two consecutive whistles. When a second individual produced a call that was different from the first individual’s vocalization, most of these calls were shorter than 1 s. However, when two consecutive calls were produced by the same individual, the second call rarely occurred within 1 s of the first. These results suggest that a second whistle may be produced by a different caller in response to the first whistle; however, in the case of an absence of a response, the first caller is likely to give further whistles. The results of this acoustic analysis show that the dolphins used in this study mostly used signature whistles during the recorded vocal exchanges.
