New Yorkers could start texting 911 by next summer — more than two years after the city originally expected to launch the new emergency system.

Advocates for the deaf and other New Yorkers unable to make emergency voice calls say the new text-to-911 service, which was supposed to be available in early 2018, can’t come soon enough.

Current 911 services aren’t accessible for the estimated 208,000 deaf and hard-of-hearing people who live and work in the five boroughs. Texting 911 would also help people with communications or speech disabilities, as well as victims of domestic violence who may feel unsafe calling 911.

“The agencies involved should be embarrassed and ashamed of themselves,” said Lourdes Rosa-Carrasquillo of disabled advocacy group CIDNY at a Council oversight hearing on the system Tuesday. She wears a hearing aid and couldn’t understand what 911 operators were saying after calling on two instances.

“They kept yelling, which only made it more difficult for me to understand,” Rosa-Carrasquillo said.

Margaret Arnold, a deaf interpreter, described in sign language a terrifying moment when she was stranded outside Washington, D.C., and could only reach 911 when someone else called for her.

“I texted 311 services for New York City … I said, ‘I need help, please,’” she signed for an interpreter. “(The) 311 (operator) said, ‘Call 911.’ I said, ‘I can’t call 911, I’m deaf. What do I do?’ (The 311 operator) said, ‘I don’t know how to help you.’”

Dennis Martinez, who is also deaf, described watching someone have a seizure in the subway and being unable to call 911 to help. “I was powerless in this situation,” he signed for an interpreter.
