@katys You still have a chance. I've been researching into Audiology as a 'back up plan' & according to an article, the average GPA ranges between 3.2-3.9. Their acceptance rate is higher than an SLP program between 35-50% chance. Being that your GPA is below that, most schools look at your last 60credits the most. Explain in your personal statement why you did horribly then point out your improved grades the last two years. I do recommend getting a high score on your GRE because you can also use that as another backup. Spend a huge amount on tailoring your personal statement/letter of intent AND letter of recommendations to the schools you'll be applying to. You might not win them over with great statistics but you still have a chance explaining who you are as a person.
If for any reason you did not get accepted the first round, keep in mind ...some schools actually look for returning applicants. Take for example, an SLP program in New Mexico...on their website, they stated that they choose their first round of applicants, then they look over to see if there's any second round applicants. During your break off, grab ANY opportunities to gain experience. Keep in mind that without great statistics in a competitive field, you just have to prove your passion through other things.
Good Luck!
