Voicefinder AP-SVG3000 is a maximum 8 port STT(Speech to Text) VoIP Gateway for Network based STT(Speech to Text) Application. This STT VoIP Gateway supports high quality G.722 16KHz VoIP codec beside 8KHz VoIP codec like as G.711,G.726,G.729A, etc. AP-SVG3000 provides four(4) STT VoIP module slots, and each slots supports two(2)-port STT VoIP module. The STT VoIP module provides one(1) 10/100Mbps fast ethernet port, one(1) RS232C console port for command line interface, 3.5mm analog audio input/output port, and RJ45 connector type radio interface port independently. Radio Interface is used for interconnection with radio system like as Motorola, ICOM, etc. Pin assignment for radio interface are Tx audio, Rx audio, Tx PTT, Rx PTT lines. 3.5mm analog audio output interface is reserved for future application. 3.5mm analog audio input interface can be used for network based call center STT application.

Scalability and cost effective STT solution

5G wireless network and broadband network services are rapidly expanding in the field of voice recognition, which is a core technology, in addition to cloud computing, robots, AI, and big data technology. VoIP gateways for high quality IP based voice recognition are the first step in integrating into an IP network, so be careful about introducing them. Pay close attention to the AP-SVG3000 if you need to choose products that are highly scalable and proven to be affordable. AP-SVG3000 is a 16KHz G.722 high quality voice recognition VoIP gateway that provides a clear opportunity to start small and start looking bigger.

Maximum 8 Port STT VoIP Gateway, Each Port provides Independent STT VoIP Gateway Service

The AP-SVG3000 is a STT (Speech to Text) VoIP gateway that can configure up to 8 ports of analog voice channels. At the time of introduction, AP-STT2 2-channel STT VoIP module is installed and used. When it is time to increase the number of channels, up to 8 channels can be flexibly coped with the demand for channel expansion. In addition, with the hot-swap function, AP-STT2 2 channel STT module in service can be replaced without needing to switch off the power supply in case of failure or replacement. It is a good choice for customers who want AP-SVG3000 high performance STT VoIP gateway. The STT VoIP module used in the AP-SVG3000 operates independently for each port and can support various VoIP voice codecs such as 8KHz G.711, G726, and G.729A in addition to the 16KHz G.722 wideband voice codec. The voice interface supports the radio interface (RJ45) in addition to the audio I / O interface. In addition, it supports RS232C (RJ45) interface for CLI (Command Line Interface).
