System and method for generating one-way speech signal samples
A system and method for generating one-way speech signal samples may include, in a telecommunications network, establishing a call connection between a far-end telephone and a near-end telephone. A resistance component may be selectively configured in parallel with the far-end telephone, where the resistance component has a value representative of resistance produced by the far-end telephone being off hook. A speech signal being communicated from the near-end telephone may be recorded.
1. A method for generating one-way speech signal samples, comprising:
in a telecommunications network:
establishing a call connection between a far-end telephone and a near-end telephone;
selectively configuring a resistance component in parallel with the far-end telephone, the resistance component having a value representative of resistance produced by the far-end telephone being off-hook; and
recording a speech signal being communicated from the near-end telephone.
2. The method according to claim 1 , wherein configuring the resistance component includes connecting a resistor having a value between approximately 200 Ohms and approximately 300 Ohms.
3. The method according to claim 2 , wherein connecting includes switching a switch from an open to a closed position to electrically connect the resistance component.
4. The method according to claim 3 , wherein switching the switch is performed after the call connection has been established.
5. The method according to claim 1 , wherein establishing a call connection includes establishing a call connection with the near-end telephone, the near-end telephone being configured with a microphone for hands-free communications.
6. The method according to claim 1 , further comprising, after selectively configuring the resistance component, configuring the far-end telephone in an on-hook configuration, and wherein recording the speech signal is performed after configuring the far-end telephone in the on-hook configuration.
7. The method according to claim 1 , wherein recording the speech signal is performed at a communications switch in the telecommunications network.
8. A system for recording one-way speech signals samples in a telecommunications networks, system comprising:
a near-end telephone;
a far-end telephone, the near-end and the far-end telephones being utilized to form a communications path there between over a communications network;
a resistance component selectively configurable to be in parallel with said far-end telephone; and
a recording device configured along the communications path in the communications network to record a one-way speech signal sample from the near-end telephone.
9. The system according to claim 8 , wherein said resistance component is positioned at the far-end telephone.
10. The system according to claim 8 , wherein said resistance component includes a resistor and switch to configure the resistor to be selectively switched in parallel with said far-end telephone.
11. The system according to claim 8 , wherein said resistance component has a resistance within a range between approximately 200 Ohms and approximately 300 Ohms.
12. The system according to claim 8 , further comprising a network switch, said recording device being connected to the communications path at said network switch.
13. The system according to claim 8 , wherein said near-end telephone is configured to operate in a hands-free mode.
14. The system according to claim 8 , wherein said recording device is configured to record the one-way speech signal sample digitally.
