# Use Multiple Speech Servers

Language identification and speech-to-text processing can be time consuming. To increase performance, you can use several IDOL Speech Servers. The `IdolSpeechServers` configuration parameter accepts a comma-separated list of servers. For example:

    IdolSpeechServers=server1:15000,server2:15000

Alternatively, you can use a numbered list:

    IdolSpeechServers0=server1:15000
    IdolSpeechServers1=server2:15000
