China Mobile has announced the $4G$ communication tariff standards, one of which is a package tariff standard: the monthly fee for domestic calls is $39$ yuan (which includes $300$ minutes of voice calls and $30GB/$month), and exceeding the monthly fee of $39$ yuan (i.e., exceeding $300$ minutes) will be charged according to the amount of excess time. The table below shows the charging standards for the excess part. (Each voice call is charged per minute, and if it is less than $1$ minute, it is charged as $1$ minute.)

| Time $/$ minutes | $1$   | $2$   | $3$   | $4$   | $5$   | $\ldots$ |
|------------------|-------|-------|-------|-------|-------|----------|
| Call fee $/$ yuan | $0.19$| $0.38$| $0.57$| $0.76$| $0.95$| $\ldots$ |

If $x$ represents the excess time of voice calls in a certain month, $y$ represents the total call charges paid in that month, and the charging standard for the excess part follows the pattern reflected in the table, then please write the relationship between $y$ and $x$.
