API 计费有官方依据

Polly 按处理字符按月结算。主表每百万字符费率为 Standard $4、Neural $16、Long-Form $100、Generative $30；GovCloud 的 Standard/Neural 费率不同。主表不能确立读者所处区域的最终账单。 定价页同时列出服务免费量（含 Standard 每月 500 万字符），以及自 2025-07-15 起 AWS 新客户的另一套规则：最高 $200 credits、六个月 Free 计划、credits 须在开户后十二个月内用完。这些是附条件的优惠，不能合并保证每个账户同时或永久享有。 示例把百万字符对应为约 23 小时 8 分钟；这是估算，不是成品测试。 AWS 新客户开户获得 USD100，还可完成活动再获最高 USD100。Free 账户计划在六个月或 credits 耗尽时结束，以较早者为准；付费账户超过适用 credits 后产生费用。把 Polly 任务视为免费之前，须核对账户资格、余额与有效期。来源: Amazon Polly — 费率与附条件免费优惠 · AWS — Free 与 Paid 账户计划
